Annabeth Chase is one of the main characters of Percy Jackson and the Olympians and The Heroes of Olympus books and is a supporting character in Magnus Chase and the Gods of Asgard. She is the demigod daughter of a mortal man named Fredrick Chase and Athena, Greek Goddess of Wisdom and Warfare, the niece of Randolph and Natalie Chase and the cousin of Magnus (who like Annabeth, is also a demigod, but is Norse rather than Greek). She is also Percy Jackson's main love interest, in spite of their deity parent's distain, and also his tutor and mentor. Annabeth has had more experience at Camp Half-Blood than any other camper and is a skilled warrior.
In both film adaptions, she is portrayed by Alexandra Daddario, who also portrayed Heather Miller.
Annabeth was born in July 12, 1993 to Fredrick Chase and Athena. When she was five, Annabeth gained a stepmother and half-brothers when Fredrick married a mortal women and had two sons with her named Matthew and Bobby. Two years later, Annabeth (now seven) and Fredrick visited her uncle Randolph's mansion for Thanksgiving, where Annabeth played with her cousin Magnus whilst Fredrick argued with Randolph and their sister and Magnus's mother Natalie, causing a rift in the family and caused Annabeth to not see Magnus, Randolph or Natalie again.
Later that same year, Annabeth ran away from home, believing her family hated her because monsters kept attacking them (due to Annabeth being a demigod as they let off a scent that causes monsters to track them down). After spending some time on her own, Annabeth eventually came across two other demigods, fourteen year old son of Hermes named Luke Castellan (whom Annabeth developed a crush on) and twelve year old daughter of Zeus Thalia Grace who had also left their homes. Some time later, the trio were found by a satyr named Grover Underwood who escorted them to Camp Half-Blood (a training camp for Greek demigods), but kept taking wrong turns, causing monsters to catch up on them. When they reached Half-Blood Hill, Thalia sacrificed herself so Annabeth, Luke and Grover to get to the camp to safety.
Percy Jackson and the Olympians
The Lightning Thief
Five years later, Annabeth (now 12) first appears after Percy wakes up from his fight with the Minotaur the night before. She was nursing him back to health and quickly asked him if he knew anything about the Summer Solstice and what was stolen. However, Percy was still confused and didn't know what she was talking about. When someone knocked on the door, Annabeth filled Percy's mouth with a spoon full of pudding and Percy fell back to sleep. Percy didn't actually learn her name until Grover took Percy to see Mr. D and Chiron called Annabeth over and asked her to make sure his bunk in Cabin 11 was ready. Instead of commenting about how cool he was like he thought, Annabeth told Percy that he drooled in his sleep before heading off to the cabin. Percy then met her out front of Cabin 11 (where the demigod children of Hermes, demigod children of minor gods and demigods of an unknown parentage lived) and saw she was reading an architecture book in Greek. When Percy entered the cabin, he was asked if he was regular or undetermined, to which Annabeth answered that he was undetermined. When Luke welcomed Percy, Annabeth began to blush but hid it when Percy noticed.
Annabeth quickly dragged Percy from the cabin and begins to get mad at him. She insults herself for thinking that Percy was the one she was waiting for and explains that any other demigod would have loved the chance to fight the Minotaur. She also explains to him how monsters never really die, as they don't have souls and will eventually reform in Tartarus. When Percy questions why he can't just pick a cabin, like one of the empty ones, which are Zeus' Cabin, Poseidon's Cabin, Hera's cabin, and Artemis' Cabin, she explains that the cabin depends on who the demigod's dad/mom is. When Percy says that his father is dead, Annabeth says he isn't dead or Percy wouldn't be at Camp Half-Blood. When Percy tries to deny this, Annabeth correctly guesses that Percy had been kicked out of a lot of schools, moved around a lot, he has Dyslexia, and most likely ADHD. Before she can go on, a daughter of Ares named Clarisse La Rue interrupts and Annabeth introduces her. When she tries to initiate Percy into the camp, Percy gives Annabeth the Minotaur's horn, but he is quickly overpowered by Clarisse. Annabeth watched through her fingers as Clarisse almost dunked his head in the bathroom toilets, but Percy controlled the water to force Clarisse out the door. Annabeth was also soaked, but she wasn't forced out. She then commented that she wanted Percy on her team for Capture the Flag. She then showed him the rest of the camp before leaving to train and saying that she would ask Chiron to allow Percy to see the Oracle, showing interest in getting her own quest and having some knowledge of a possible war among the gods.
Later when talking to Luke about people saying he was Big Three material and Annabeth calling him the one she was waiting for, Luke said that Chiron was given a prophecy by the Oracle saying that Annabeth wouldn't be ready for a quest until a certain someone arrived at camp. He also mentioned that Annabeth acted like that to every new camper. Percy saw her later at dinner with the rest of Athena's Cabin. Percy from then on took Ancient Greek with Annabeth and learned other self-defense type classes. While the cabins prepared for Capture the Flag, Annabeth and two of her siblings came in with the banner of Athena as their flag, while Clarisse and her siblings came in with the banner of Ares.
During the game, Annabeth lead the blue team and used Percy as bait for Clarisse, knowing she would want revenge on him. After Percy managed to defeat Clarisse, Annabeth took off her invisibility cap to show she had been there. While Percy was annoyed at her for using him, she claimed she was about to jump in, but Percy managed to handle it on his own. When Annabeth notices the wound in his shoulder healing as he stood in the water, she quickly figures out that Percy is a son of Poseidon, but had assumed that Zeus would have been the one to break the oath. Before she can explain it to him, a hellhound attacked. Annabeth stepped in front of the monster, but it jumped over her to attack Percy. The hellhound was quickly defeated by Chiron, but not before injuring Percy. Annabeth told the others to put Percy in the water, which quickly healed his wounds and Annabeth pointed out the symbol of Poseidon hovering above Percy's head.
Later, after Percy visits the Oracle and gets a prophecy, Chiron explains that the gods are on the brink of war because Zeus' Master Bolt had been stolen and is blaming Poseidon for it. When Grover Underwood volunteers to help in the quest, Annabeth quickly takes off her cap and volunteers as well, revealing she had heard the entire conversation. She claims that while Athena and Poseidon aren't on the best of terms, she is the best person for preventing him from messing up, calling Percy "Seaweed Brain." The next morning, Annabeth got ready for the quest by bringing her cap, her knife, and was given some supplies by the camp before leaving for New York City. Before leaving, Luke gave Percy a pair of winged shoes and gave Annabeth a goodbye hug, which almost made her pass out.
After being driven into the city by Argus, they are quickly found by the Furies while taking a bus to New Jersey. Annabeth used her cap to hide Percy from them in hopes that Percy's smell will hide her and Grover's sent. Percy snuck past them, but the Furies went after Annabeth, violently demanding to know where "it" is. Percy hit the brakes and the bus crashes due to the fighting between the demigods and the Furies. The three escape and Annabeth wonders what the it the Furies wanted was, as if they were talking about Percy, they would have said he. However, being tired and without a ride, they find their way to Aunty Em's Gnome Emporium. While Percy and Grover quickly fall for Aunty Em's kindness, Annabeth becomes suspicious and soon realizes that the old woman is Medusa. Annabeth becomes extremely worried because it was her mother that turned her into a monster because she was caught kissing Poseidon in one of her temples. When Medusa (Aunty 'Em') wants to take a picture with the three, Annabeth realizes that Medusa is trying to turn them into stone so she instantly warned them to look away before turning invisible and pushing Grover and Percy down. During the fight, Annabeth convinces Percy to kill her as she knows he has the better weapon and because Medusa hates her and her mother, Athena. After Percy killed Medusa, Annabeth walked up to it and covered the head in a dark veil so they wouldn't see it's eyes. Percy then ships Medusa's Head to Mount Olympus by Hermes' delivery.
While camping in the woods, Percy figures out that Grover was the satyr that tried to get Annabeth, Thalia, and Luke back safely, but ultimately failed. The next morning, Annabeth woke Percy up and made the group breakfast, while Grover found a lost poodle that they could return for the reward money, allowing them to buy train tickets to St. Louis, Missouri. During the trip, Annabeth asked Percy (who had a dream about Kronos) who he won't help, as he said that in his sleep. Percy explained the dream, and Annabeth began to have doubts that Hades was the one that took the Master Bolt as everyone had originally thought. She also told him he couldn't make deals with Hades, but Percy asked her what would happen if Hades took her father. This angers Annabeth and she explodes, saying she would leave her dad to rot and revealing a little about her past in the process, saying she hated her family, despite keeping her dad's ring. However, as soon as she sees the Gateway Arch, she brightens up and reveals that she hopes to one day become an architect and building something that would last for a thousand years. Once in the station, Annabeth took Percy and Grover to the Gateway Arch and got to the top shortly before closing time. While at the top, a large woman with a small dog asked about their parents, to which Annabeth told her that they were scared of heights. Shortly after, Annabeth went downstairs with Grover and waited for Percy, not knowing the danger he was in. They watched as Percy fell from the arch in an explosion and landed in the nearby river. Annabeth and Grover ran to him, with Annabeth trying to look mad, but really being relieved that he was not harmed.
After getting on a train out of the city, they arrive in Denver and Annabeth showed Percy how to Iris Message. They get a hold of Luke instead of Chiron, and he informs them that the camp is becoming a battle field with cabins picking sides in an upcoming war. Annabeth on the other hand messes with her hair and tried to make herself look prettier for Luke, however the connection is cut short soon after. While at a diner, Ares appeared before them and offers them a ride west if they get something for him in Waterland. Percy and Annabeth are reluctant because the item is in the Thrill Ride O' Love and neither feel comfortable. Once they are inside, a trap made by Hephaestus is activated and hundreds of thousands of metal spiders flood the room and Annabeth is paralyzed with fear. Percy floods the room with water from the pipes and they sail toward the exit, but the gate is closed. Annabeth uses her brain to figure out when the best time to jump was and they make it out safely (Percy noting that if they jumped when he thought they should, they would have smashed against the gate). When they return the item, Ares allows them to climb into the back of a Kindness International truck, which transported animals.
While in the truck, the find that Kindness International are smuggling animals and they try their best to help the animals. Annabeth and Grover tell Percy the full story of how they made it to camp and how Thalia sacrificed herself. Annabeth also says that she doesn't blame Grover for what happened and neither did Thalia, also calling him the bravest satyr she knew. After Grover fell asleep, Annabeth talks about the beads on her necklace and eventually opened up about her rocky relationship with her father, explaining the ring on it. When Percy asked her if she would side with her mother if she went to war against Poseidon like they did during the Trojan War, Annabeth told him that she would side with him as they are friends. The next morning when Maurice (one of the truck drivers) went to go feed the animals, Annabeth put on her cap and started banging on the outside, distracting the driver long enough for Percy and Grover to free the animals.
While in Las Vegas, they eventually arrive at the Lotus Hotel and Casino where they are given key cards and decide to have spend the night and play some games while they're there. Annabeth gets really into an architecture game and can't bring herself to pull herself away, even after Percy tells her it is a trap. She doesn't budge until the word "spider" is said and she comes to her senses.
Once arriving in Los Angeles, Annabeth, Percy, and Grover are chased into Crusty's Water Bed Palace, where Annabeth and Grover are quickly trapped by a monster called Procrustes, who stretches out anyone to the exact length of the bed. While Annabeth pleads for Percy to help her, he is forced to outsmart the monster and eventually traps him in one of his own beds, freeing Annabeth in the process. Percy then grabs the address from Procrustes' address book and the three head to DOA Recording Studios, the entrance to the Underworld.
Once reaching the Underworld, they couldn't think of a way to get to Hades without passing Cerberus, until Annabeth pulled out a rubber ball and began to play fetch with him and claiming she used to train a Doberman Pinscher. She played fetch long enough for Percy and Grover to pass by and then followed them telling Cerberus she would play with him again sometime and he whined as she left. After passing the large dog, Grover's shoes began to act up and began pulling him toward Tartarus, the deepest part of the Underworld. While thinking he was only messing around, Annabeth quickly jumped to action along with Percy as they pulled him. Annabeth suggested they untie the shoes, but Grover was only saved when his fake feet fell off and the shoes flew into the pit. Annabeth, knowing what the pit was suggested they all back away as soon as possible.
When they arrived at Hades' Palace, Annabeth was respectful to Hades and informed him of a war approaching among the gods, but Percy quickly asked for the Master Bolt back from him. Hades erupts into anger at this, claiming that Percy not only took the Master Bolt, but his Helm of Darkness as well. Annabeth tried her best to figure out what all this meant, but failed to see the connections. When the Master Bolt appeared in Percy's backpack, Annabeth becomes even more confused. Percy pulled out three pearls that his father had given him to escape the Underworld, and Annabeth offered to stay so Sally Jackson could go. Eventually, Grover, Annabeth, and Percy returned, leaving Percy's mom behind. Once back on the surface, Annabeth apologizes for leaving Sally behind.
However, Ares soon appeared and revealed that he was the one that hid the bolt in the backpack, and the one that wanted the gods to go to war. Percy challenged Ares to a fight, much to Annabeth's protests, but she gave him her necklace for luck. Annabeth watched the battle with Grover and warned them when policemen had arrived, but Ares caused a wall of fire to appear in front of them. When Percy managed to get Ares to retreat, Annabeth warned Percy not to look at Ares' Divine Form. After taking the Helm of Darkness from Ares and giving it to the Furies, Annabeth and Percy both figured out what was in the pit.
The three flew back to New York and Percy sent Annabeth and Grover back to Camp Half-Blood to tell Chiron what had happened. Also because if the gods didn't believe Percy's story, Chiron woul'dve wanted to keep them away from danger. After the Master Bolt was returned to Mount Olympus and all seemed well, Percy returned to camp and celebrated a successful quest with Annabeth and Grover around the campfire. They even set up a picnic as Grover left to go search for the lost god Pan, with Annabeth giving him a goodbye hug. However, when Percy was poisoned by Luke and revealed himself to be an agent of Kronos, Percy woke up the next morning in the Big House with Annabeth tending to him once again, mirroring Percy's first arrival at camp. He explained what had happened with Luke, causing Annabeth to become shocked and then angry at him, cursing his name. Annabeth then spends her time helping Percy recover and admits that she will spend a year with her dad, as she had sent a letter to him shortly after arriving at camp. Percy and Annabeth then say their goodbyes, calling the other Wise Girl and Seaweed Brain respectively.
The Sea of Monsters
A year later, Annabeth returned once again to help Percy save the camp, though this time as friends, the previous tension between them as a result of their parentage was resolved by Percy's offer to put their differences aside. Annabeth arrives at Percy's new school to tell him what has happened at camp, but is wearing her cap so no one notices her. It is also found out that Percy carries around a picture of her which makes some of the other kids pick on him. During gym, a group of Laistrygonians attack Percy, but Percy along with Tyson fight them off and Annabeth stabs the last on the back making her presence known. She then takes Percy and Tyson (reluctantly) with her to camp using the Gray Sisters' Taxi. While at camp, Annabeth and Percy decide to work together to make a chariot (like their parents) for the upcoming Chariot Race, but because of Annabeth's fear of Tyson, they have a fight and work on their own chariots. They do make up after an attack by some Stymphalian Birds because Thalia's tree is dying and the borders are weakening. After a dream Percy has, Annabeth realizes that Grover found the Golden Fleece and ask Tantalus for a quest to get it, but he gives the quest to Clarisse. However, that night they sneak aboard a ship passing by the camp (with some help from Hermes and Poseidon) to search for the fleece themselves. The ship they arrive on is the Princess Andromeda. A monster ship with Luke on it and they are forced to escape. Annabeth leads them to an old hideout used by her, Luke, and Thalia. She also tells Percy after sending Tyson outside why she hates cyclopes, until Tyson comes back with a hydra nearby. After battling the hydra with little effect, Clarisse arrives and takes them with her on her ship, the C.S.S. Birmingham, to the Sea of Monsters. After entering the sea, Percy and Annabeth are split up from everyone else when Clarisse's submarine explodes and arrive at C.C.'s Spa and Resort. While Annabeth is given a full makeover, Percy is turned into a guinea pig. Annabeth outsmarts Circe and uses one of Hermes' multivitamins to turn Percy back and make them immune to magic for a short time. She then puts her knife to Circe's neck, and threatens her. They escape using Blackbeard's ship. Annabeth hears the Sirens' song while on the boat, and although she'd convinced Percy to tie her to the mast, he forgot to disarm disarm her and she got hypnotized by the song. The song showed her the things she wants most; her parents together, Luke as his normal self, and a redesigned Manhattan. It is confirmed that her fatal flaw is hubris (pride), being a child of Athena.
They eventually make it to Polyphemus' island where Grover and Clarisse are being held captive (and finding Tyson along the way). In order to provide a distraction, she puts on her invisible Yankees cap and tells the cyclops she is "Nobody," angering him to no end as he smashes rocks and stops around, eventually capturing her. She is freed when Percy tells Polyphemus he is "Nobody," since Annabeth was a girl. He lets he go and Percy manages to defeat his half brother and take the fleece. They all eventually sail out of the Sea of Monsters and Annabeth and Percy give Clarisse enough money for a plane ticket back to camp. After she leaves, they are attacked by Luke for the fleece, but when he finds out they don't have it, Annabeth is forced to watch Luke and Percy fight each other. Percy manages to trick Luke into revealing he poisoned Thalia's Tree by sending an Iris Message to Camp Half-Blood behind Luke and getting him to admit he did it, proving that Chiron was innocent. Chiron and the Party Ponies come to their rescue and they return to camp.
Annabeth and Percy teamed up to win the chariot race waged between the cabins of the camp. Following their victory, Annabeth's perpetual facade of calm cracked slightly when she kissed Percy on the cheek. Afterward, while Annabeth is doing patrol for the camp, the fleece's magic works too well, causing Thalia's pine tree to 'give back' Thalia's spirit, causing Thalia to come back to life (though she wasn't really dead).
The Titan's Curse
Six months later, Annabeth, Percy, and Thalia enter a school looking for two demigods that Grover had been looking after. They are stopped in a hallway by Dr. Thorn and Ms. Gottschalk, but Thalia uses the Mist to convince them they were students. He lets them pass and the three go to the dance looking for the demigods and Grover. Annabeth and Percy start dancing and Annabeth says she has something very important to tell him, but are interrupted when Nico and Bianca disappear. Annabeth goes to get Thalia and Grover while Percy rushes off to find the demigods only to be captured. When Annabeth and Thalia attack Dr. Thorn, the Hunters arrive to help fight it off. During the fight, Annabeth jumps on Dr. Thorn's back to stab him, but they both end up going over a cliff and vanish. Artemis says she will track down Dr. Thorn as the Goddess of the Hunt and she ordered the Hunters to go to Camp Half-Blood. Percy has a dream that Annabeth sees Luke holding up the sky and pleading for Annabeth to take it from him. Annabeth does so, right before the 'ceiling' collapsed on him, and Luke walks away, leaving her there alone. When he wakes up, Grover tells Percy that Annabeth was asked to join the hunters and that was what she wanted to talk to him about at the dance.
Later, Percy has another dream where Annabeth is still holding the sky and in order to trap Artemis, he tells her that if she doesn't take the sky from Annabeth, she will surely die from the weight. Artemis takes the sky and Annabeth falls to the ground and carried away by Luke who decides to use her as bait for the other demigods. The Oracle of Delphi gave one of her ever-cryptic prophecies, and off went Percy, Thalia, Grover, Bianca di Angelo, and the Huntress, Zoë Nightshade, in pursuit of Artemis and Annabeth and the monster which Artemis was chasing after. Aphrodite, Goddess of Love and Beauty, convinced Percy that his love for Annabeth was worthwhile, though she also made it incredibly harder for them to fall in love. Though Percy was originally not included in the quest, Nico di Angelo pleaded to him and convinced him to follow them to protect his sister, Bianca. He was seemingly unable to leave the fate of his best friend in the hands of others. After a prolonged quest, which included the loss of Bianca in the Junkyard of the Gods battle to a prototype of Talos made by the forge god Hephaestus, the group arrived at the ruins of the Titans' palace, Mount Othrys in San Francisco, California, and found Annabeth, with a grey streak in her hair as a result of holding the sky and Artemis, who was struggling under the weight of the sky; both captives of Luke and Atlas.
Upon the re-imprisonment of the Titan General Atlas, the death of Zoë, and the apparent death of Luke (or so they thought, except Annabeth), Annabeth was saved by Percy and the others, along with her mortal father, Frederick Chase who attacked the monsters chasing the group using the celestial bronze bullets that he had made from things Annabeth had left behind when she ran away from home. Also, Annabeth's stepmother shows care for Annabeth in this book when she tells Percy that even though she knows that Annabeth is a demigod and can't live in San Francisco because of Mount Orthys, the Titan base camp, she still has a home with them and can come anytime she wants.
It is strongly hinted in this book that Annabeth was considering to join the Hunters of Artemis at the book's beginning, which is what she might have intended to tell Percy during their dance at Westover Hall, only for her to get interrupted. This theory is further supported by Percy later finding a Hunter brochure in her backpack, and Aphrodite later telling him that Annabeth was close to joining the Hunters ranks. By the end of the book, however, Annabeth has clearly changed her mind on the subject.
The Battle of the Labyrinth
Annabeth is now 14 years old. She and Percy were supposed to go to the movies after his orientation day into his new school, Goode. However, their plans are interrupted when Percy blows up part of the school in a fight with some monsters, Kelli and Tammi, who were empousai in the forms of cheerleaders. Her possessiveness for Percy is revealed when she becomes annoyed at him after she finds him escaping with the mortal girl Rachel Elizabeth Dare. She has a fight with Percy and refuses to speak to him during the Gray Sisters' Taxi journey to Camp Half Blood. Once back at camp, Percy and Annabeth accidentally discover an entrance to the Labyrinth under the rock pile known as Zeus's Fist while on a camp game designed personally by Quintus. She realizes that Luke can use this entrance to invade the camp at any moment unexpected. Annabeth leads the quest into the Labyrinth, fulfilling one of her many ambitions at last. While studying the Labyrinth, Percy walks in on her. Annabeth was frustrated and held out her arms so Percy could give her a hug. He remarks that her hair smelled like lemon soap.
Later, Annabeth descends into the Labyrinth with Percy, Grover, and Tyson (Percy's half brother and a very good Cyclops) to find a way to stop Kronos' evil forces from invading the borders of Camp Half-Blood by searching for its inventor, Daedalus. The Oracle of Delphi gave her a prophecy which appears to have scared her and she refuses to say the last line. As they go into the Labyrinth, they face and fight many monsters. Annabeth faces a Sphinx and finds its riddles (which were actually factual questions) not challenging enough and an insult to her intellect. They escape the claws of the Sphinx and continue on to find Hephaestus in one of his many forges so he can tell them about where to find Daedalus and his workshop in the Labyrinth. Annabeth believes that Percy will die when Mount Saint Helens erupts but right before he goes in she kisses him for good luck.
Percy was instead marooned on the phantom island of Ogygia when he tried his best to fight the telekhines, half-dog half-monsters, who were perpetrating Hephaestus's once favorite of all of his many forges, where the sad but seductive Calypso resides. When Annabeth sees Percy return (while she is burning his shroud, believing him to be dead) she hugs him fiercely, but quickly lets go when she realizes she is making a big scene in front of all the other campers. When she finds out what happened to Percy after he tells her and Chiron in Chiron's office in the Big House, Annabeth angrily exits after guessing where he was stranded and obviously feeling jealous. Percy asks mortal Rachel Elizabeth Dare, much to Annabeth's dismay. Annabeth makes several offending remarks toward Rachel, who simply shrugs them off and after a long while, Annabeth accepts her as their guide. The three of them discover Luke, who has become Kronos' vessel, which saddens Annabeth. After the Battle of the Labyrinth from the entrance of the Labyrinth under Zeus's Fist in the woods, Luke and his army are forced back into the Labyrinth, leaving after causing many, but only two named, casualties.
The Last Olympian
Annabeth joins forces with the campers and goes to New York City to save Manhattan and Mount Olympus (over the Empire State Building) itself from Kronos' Titan army army the Battle of Manhattan. At one point, she takes a poisoned knife for Percy, that Ethan Nakamura was using to try to stab him. Even though she does know Percy was invincible, Annabeth jumps in the way and takes the stab, defenseless. It is later revealed that if she hadn't taken the dagger for Percy, he would have died, because his only weak spot, the small of his back, was Ethan's target though it is unknown how Ethan knew about the weak spot it or Ethan may have not been aiming for any spot in particular as he told Kronos. Percy gets Blackjack, his black pegasus, to fly her away, takes Kronos on, and is forced to retreat. When Percy checks on Annabeth, he decides to tell her where his Achilles heel is. Annabeth is the only person that knows where it is besides Percy. While Annabeth is resting because of the poisoned knife, she tells Percy that Luke had visited her before they went into the Labyrinth, explaining why Hermes, the messenger of the gods, the patron of thieves, and others, was mad at her for not saving Luke when she had the chance to, and she also states that Percy looks "cute" when he is worried. When it is discovered that Silena was the spy, Percy describes Annabeth looking as if "The world had just been pulled from underneath her feet."
Annabeth saves Percy and Olympus by finally realizing for whom the prophecy is truly meant for: Luke. During the battle against Kronos, Annabeth is able to get Luke back to his senses by bringing up a promise he made to her when they first met that he (and Thalia) would be her family. She tells Percy to give Luke her knife (that was Luke's gift to her when she was seven) so he can stab himself, which would banish Kronos back to Tartarus though there is no evidence to where the spirit of Kronos went to after Luke sacrificed himself since they were up high above Manhattan in the Hall of the Gods in the Olympian gods throne room on Olympus. Before he dies, Luke asks Annabeth if she loved him to which she replied that to her, Luke was like a brother but she didn't love him to which Luke nodded as if he expected Annabeth to say that. Following this, Annabeth is rewarded by Athena, now being able to fulfill her dream and design for the gods a new city on Olympus, as the old one was ruined by the battle (actually destroyed by Kronos when he invaded Olympus through the Empire State Building, entrance to Olympus). She is also allowed to design the new cabins at Camp Half-Blood.
She and Percy celebrate his 16th birthday privately, in the apparently empty dining pavilion of Camp Half-Blood. Percy attempts to tell her that he has strong feelings for her, but she is amused, up until the point he states that she is not making it easy for him to admit it. She laughs and warns him that she will never, ever make things easy for him, and that he should get used to it, wraps her arms around his neck, and kisses him. Percy said that it felt like his brain was melting through his body, and that he could have stayed like that forever, until Clarisse La Rue and several other nosy campers eavesdrop on the whole episode and throw Percy and Annabeth into the camp's canoe lake. However, Percy creates an air bubble deep under the surface of the lake, because he is a son of Poseidon, and they share, as Percy describes it, "the best underwater kiss of all time." At the end, Percy is relieved that Annabeth is staying in New York and they leave Camp Half-Blood together.
The Heroes of Olympus
The Lost Hero
Annabeth appears in a chariot pulled by pegasi with Butch, a demigod son of Iris, the carrier of messages through rainbow "Iris-messages" for the gods and the Rainbow Goddess, to pick up the three demigods Jason Grace, son of Jupiter, Piper McLean, daughter of Aphrodite, and Leo Valdez, the son Hephaestus. It is revealed she and Percy are still dating. Annabeth and Butch, went to the Grand Canyon in search for Percy, who has been missing for three days. Annabeth had been receiving visions from Hera, that a hero with one shoe, which she finds out is Jason, will solve her problems, which is finding Percy. She is also shown frustrated and worried with Percy's disappearance. Before leaving the Grand Canyon, Annabeth yells to the sky, "What do you want from me? What have you done with him?" Annabeth gives Piper a tour of Camp Half-Blood, also letting Piper choose her weapon Katoptris, then explaining that Piper's relationship with Jason at the Wilderness School was an illusion due to the Mist and wanting to give Piper a chance to break down privately when she realized the same thing, though she has been holding herself together as well, it is obvious that Annabeth is equally crushed at losing Percy so mysteriously.
When Jason is given his quest to rescue Hera from the capture of Polyphrion the giant, Annabeth refuses to accompany the quest group, partly because the prophecy states that children of Hephaestus, Jupiter/Zeus, and Aphrodite will go instead, and partly out of her own distaste for Hera. Instead, she uses the time they are gone to continue her search for Percy.
After the quest group returns and relates their findings — the rise of the giants, the attempted return of Gaea, and the fact that Jason was "exchanged" to the Greek Camp Half-Blood — Annabeth puts everything together and realizes, as Jason has, that Percy has been taken to the Roman Camp called Camp Jupiter as the corresponding half of the exchange. She vows to accompany Jason, Piper, and Leo when they journey there to retrieve him.
The Son of Neptune
While Percy Jackson is running away from the gorgons, Stheno and Euryale, he sees San Francisco, which reminds him of Annabeth, the only person he can remember from his past. Also, when Percy talked to Lupa, she told him that if he completed his quest, he would see Annabeth again soon.
Before Percy goes on his quest to free Thanatos, he has a dream and sees Annabeth. She tells him to stay atCamp Jupiter because Tyson and Mrs. O'Leary are close by and are trying to find him. When Percy wakes up, he feels bad that he will have to ignore Annabeth and go on the quest anyway as the Roman campers need him. During his quest, Percy has flashes of memory about Annabeth, as when he looked at Mount Tam, he remembered the fight with Atlas and he told Frank and Hazel he had been their once looking for Annabeth. Later when looking for Ella in a library, he said Annabeth would like this place as it was quiet and filled with books. He later remembers that she loved architecture.
After completing the quest, Hera appears to Percy in his dream. She tells him that Annabeth will cause him trouble in the future. When Percy says that Annabeth is the person he most wants watching his back, Hera says "We shall see," and tells Percy that she will have a hard task ahead of her when he arrives in Rome and that she may not be up to it.
The next morning, Percy arrives in the Senate meeting to discuss the arrival of the Argo II, which they will allow to land. As he goes to meet the ship, he says he knows Annabeth is on board and this could be the best day of his life if everything went right.
The Mark of Athena
As Annabeth approaches Camp Jupiter on board the Argo II, she checks the ship to make sure that everything is set up, including the back-up plans to the back-up plans. She tries her best to keep Gleeson Hedge under control, while watching Piper McLean practice her lines for the meeting. When Piper repeats the line for the Romans to lay down their weapons, as the Greeks only wanted to talk, her Charmspeak almost causes Annabeth to lay down her knife, and have a chat. She also watches Leo Valdez fiddle with the controls of theArgo II.
While watching Jason Grace prepare for the meeting, she could not help but not trust Jason, as he always seems too perfect. She thinks maybe he would turn them in as prisoners once they landed and give the ship as a gift. Also, whenever she looks at Jason, she remembers how much she misses Percy. She wishes she could talk to her mother for help, but it was impossible after an encounter a month earlier with her, where Annabeth had received a horrible present. Annabeth also mentions feeling a mysterious chill, as if "an evil snowman had crept up behind her and was peering over her neck."
An explosion nearly knocks Annabeth overboard, and Terminus, the Roman God of Boundaries, appears on theArgo II. He shrieks that he will not allow weapons inside the Pomerian Line. Annabeth tries to regain control of the situation and calm everyone down by introducing herself to Terminus, who finds that Annabeth being the daughter of Athena, the Greek form of Minerva, is "scandalous." But before Annabeth can question Terminus on what he means, Jason interrupts and asks for permission to land inside the Pomerian Line.
Annabeth spots Percy Jackson walking with Frank Zhang, "a boy with a black buzz cut" and Hazel Levesque, "a girl wearing a Roman cavalry helmet," like they were best friends. She also notices that he is now a Praetor, which makes her heart do a gymnastics routine.
Annabeth orders Leo to stop the ship as she asks Terminus whether there is a rule against the ship hovering over New Rome. She explains that technically the ship will not be touching Roman soil, and suggests they use a rope ladder to get down to the Forum, promising Terminus that all their weapons will stay on the ship as long as the legion reinforcements will honor the same rules. When questioned by Leo, who asks if this is a good idea, Annabeth clenches her fists to stop them from shaking. She feels a cold presence, which seems to be laughing at her and the bad choices she is making. But she knows Percy is down there, and that she has to see him. She replies, it will be fine and Terminus will make sure that both sides will obey the rules, if Terminus agrees. Terminus sniffs, but agrees to "for now," and allows them to climb down the ladder to New Rome, but pleads them to not destroy his town.
Annabeth descends with the rest of the Argo II's crew where she spots Tyson and Mrs. O'Leary, and Reyna, whom she finds reminding her of herself. Just as Reyna Avila Ramírez-Arellano begins to give a welcoming speech, both Percy and Annabeth surge forward and hug and kiss each other, before Annabeth flips him over onto his back as she channels all her bitterness and worry about him into her judo flip. Reyna jokingly asks if Annabeth is actually a Roman or an Amazon before inviting them to their welcome feast. But Annabeth still cannot shake the feeling that something is about to go terribly wrong. They all tell stories of the quests they have been on, and Annabeth is surprised at the revelation that Hazel and Nico are related. Annabeth helps in stopping Octavian from taking Ella the harpy, when she accidentally blurts out a prophecy, by ridiculing Octavian's idea that harpies can tell the future.
While Reyna is walking with Annabeth through New Rome she calls for her dogs, Aurum and Argentum. The girls discuss the differences between Minerva and Athena. Reyna notes there are no children of Minerva at the camp due to Minerva being a virgin goddess, and that if they were to come to Camp Jupiter, they would be artists and not warriors or leaders on quests. Annabeth then realizes that she had met Reyna before at Circe's Island. They walk all the way to the Garden of Bacchus and appreciate the view. Reyna explains that she wanted to talk to Annabeth to learn the truth. Instead of Annabeth feeling bad about her not being able to trust anyone at camp, she talks about her family, growing up, and adventures in Camp Half-Blood.
Throughout the conversation, Reyna mentions that when she was on Circe's Island, she had met a son of Athena who washed up on the shore and was rambling about the Mark of Athena. Then, a large explosion makes a crater in the forum of New Rome. The Argo II then continues to attack the city. Reyna and Annabeth rush down to the Forum. Since Roman's are not allowed any weapons inside the Pomeranian Line, they had started to throw food, rocks, and plates at the Greeks. Piper and Jason try to calm the angry mob by telling them they would never attack New Rome, but fail. Right outside the Pomeranian Line the Roman's were set up catapults to fire on the attacking Argo II.
Annabeth sees Percy using water from a fountain to douse the angry mob of Romans. Octavian comes down the leader screaming that Leo has fired on everyone. Percy asks if Hazel and Frank are coming with them on the ship, and they say yes. Hazel calls for Arion and distracts the crowd by riding straight through it. Frank, in attempt to let Percy and Annabeth climb the rope, changes form into a dragon. Once Percy and Annabeth are up, Leo is tackled to the ground by Percy and falls on his head. Annabeth then takes charge of the ship and leaves Camp Jupiter as quickly as possible.
Annabeth interrogates Leo, but is called down to check on Jason, when she returns Leo tells them that they need emergency supplies to repair the ship and they land near the Great Salt Lake, in Utah. Percy and Annabeth ride Frank, in the form of a dragon, into Salt Lake City to get tar, although they run into some tar monsters, they return safely with a big bucket of tar. The demigods hold a conference in the mess hall, Piper tells them about her visions that she has seen in her knife. Unable to figure out what the visions or prophecies mean, they decide to visit Kansas, where Piper saw a strange man, Bacchus is standing in front of a sign saying 'Topeka 32'.
Leo needs Annabeth to help him repair the hull, but Percy promises to come back to her. When they return, Annabeth and the rest of the crew are surprised when Piper returns on Blackjack with two unconscious demigods. Piper explains what happened; the conversation with Bacchus who told them to go to Atlanta and findPhorcys, the trap sprung by Gaea and the eidolons and both Percy and Jason thank her for saving them. They work out what Gaea wants, the blood of two demigods, one male and one female, to water the stones of Mount Olympus and wake Mother Earth. Piper removes the eidolons from all three boys' bodies, and makes them swear on the River Styx that they will never return to this ship or possess any member of their crew.
In the middle of the night, Annabeth sneaks into Percy's cabin and wakes him up. They go down to the bottom of the ship where the stables are, which reminds her of their first quest when they were traveling in the truck full of zoo animals. Percy asks her why she is nostalgic about that, but she says it was the first time they actually talked, and when she decided to like him. They kiss, and then fall asleep.
The next morning, Frank finds them and is terrified that Coach Hedge is going to kill them for sneaking out, as everyone thought they had been kidnapped. They have a conference and Percy tells them his dream about the twin giants, Otis and Ephialtes, and Nico di Angelo suffocation in a bronze jar.
Percy and Frank decide to find Phorcys, Percy also wants to take Annabeth but Coach Hedge declares that she is grounded. He volunteers himself for the expedition. When the trio return, Annabeth was trying to amuse Hazel by telling her about Percy's greatest 'Seaweed Brain' moments. Leo sets course for Charleston, whilst Percy and Frank tell the demigods what happened, with Hedge interjecting from time to time. They discuss why they are heading to Charleston, to find a map, Percy suggest for 'The Mark of Athena' but Annabeth seems to be projecting a 'I don't want to talk about it' vibe, so Percy doesn't elaborate. Jason tells them that at Charleston, there is a museum full of Confederate ghosts, where he, Leo and Frank volunteer to visit. He also mentions the Battery park near the harbor, where there was a ghost or spirit dressed like a Southern Belle from the Civil War, Reyna went up and talked to it but when she came back she was shaken and never acted the same way around him. Annabeth decides to have a girls' adventure with Piper and Hazel.
Annabeth thinks about the last time she met her mother, in her Roman form as Minerva. Annabeth tries to get her attention by calling her Athena, but the goddess dreamily replies that 'that was my name, before they sacked my city, took my identity, made me this.' Athena tells Annabeth to avenge her, and destroy the Romans because they were dishonorable and copycats. Hera said that they must keep the two camps apart, but Athena wanted them to fight to the death, and for her children to destroy the 'usurpers'. When Annabeth argues back that she understood warfare, and was wise enough not to fight with reason, but Athena replies that now she will never forgive them, and neither would my children. She gives Annabeth a coin that looks like an old-fashioned subway token but when she looks upon it, it becomes an ancient Athenian silver drachma with the symbols of an owl and an olive branch with a Greek inscription on the other side. Athena urges her to 'Follow the Mark of Athena. Avenge me.', when Annabeth tries to explain that Percy is missing and Hera's plan to bring the camps together, the goddess implores her to kill Percy if he has become Roman, and if Annabeth joins them, then she has failed her mother already. No matter how many times, she tried to throw the silver coin away, it kept returning to her pocket like Percy's sword, Riptide. Annabeth thinks she is beginning to understand what her quest is, but prays to the gods that she is wrong.
Frank comes into Annabeth's cabin asking for help as he wants to know how to get out of the Chinese handcuffs, that he took from the Aquarium. Annabeth feels quite honored that Frank was embarrassed but looked for her help, after Leo teased him. She scans the handcuffs onto her laptop which produces a 3-D model on the screen. She shows him the solution to the puzzle, is to not fight against the handcuffs, and that the best traps are the most simple.
Annabeth, Piper and Hazel find the 'ghost' who turns out to Aphrodite, who invites her to have tea and chat, even though, according to her, war is coming and bloodshed is inevitable. Aphrodite reveals that the civil war between the Greeks and Romans doesn't affect her as much as the other gods (who seems to have split personalities), as love is universal. She tells them about why Athena was so angry when she became Roman, becoming more of a demure Goddess of Crafts and Cleverness, when they took away her military importance and the Greeks, nor Athena forgave them for that insult. Annabeth realizes that the Mark of Athena leads to a statue which the Romans took, and the children of Athena have been searching for it for centuries, starting civil wars. Aphrodite directs them to a map close by that was left by her siblings in 1861, and that Annabeth will face her worst fear.
Before Annabeth can reply, Hazel spots a pegasus pulling a chariot, and two giant eagles descending down to the dock. As they run back to the ship they are stopped by Octavian and two legionnaires. Annabeth chucks her dagger into the ocean, in a bid for Percy's help, Octavian is confused but orders the other two to lower their weapons. But Percy interrupts by flooding the dock and dragging the Romans into the sea, he tells Annabeth that she dropped her dagger. They run back to the Argo II and Annabeth and Percy pilot it to Fort Sumter. They see Frank as a giant bald eagle carrying Leo, and Jason riding the wind behind them, but Coach Hedge fires a 'warning shot' which knocks out the Roman chariot following them which then crashes into Jason and also singes Frank's wings so he drops Leo.
When Annabeth enters the fort she sees Leo firing at giant eagles, a full grown elephant who was rampaging around the flagpoles and Jason fighting Dakota before knocking him out. Fortunately there are a lot of tourists which cause chaos but also stop Annabeth from moving anywhere quickly. Annabeth gets shut in a room, only to see it swarmed by tiny black spiders. She panics and has a flashback, when she was little and spiders came at night, her step-mother tells her to stop scaring her little brothers and she's only imagining it. The spider bites fade before she gets dressed and her step-mom thought that the cobwebs were a trick. On the third night, Annabeth ran away from home. Gaea talks to her saying that although she would rather have Annabeth as a sacrifice, she will let the weaver take her revenge.
Annabeth sees a red symbol of an owl blaze on the wall and the spiders disappear. She runs towards an old artillery piece that is glowing red, and using her knife retrieves a small bronze disc, which she stuffs in her backpack. She is confronted by Reyna, with her two metal greyhounds, when she tries to explain, Reyna cuts her off and tells her to come with her quietly, where she will be trialled and then painfully executed. Or Octavian will attack Camp Half-Blood, the location of which she told Reyna, Annabeth pleads that Reyna slow her down. Reyna says she respects her as they are both daughters of war goddesses, but she believes that Annabeth's quest is doomed to fail. Reyna retreats but swears that when they meet again, they will be enemies on the battle field. Annabeth runs for the ship and Piper pulls her onto the deck.
Once in the Mediterranean Sea, Percy has a dream of Ephialtes talking with a shadowy figure about how Gaeaprefers using him and Annabeth as sacrifices. Percy wakes Annabeth up and tells her about his dream. However, she makes him promise not to tell the others as it would only worry them, as she has already figured out what is waiting for her at the Athena Parthenos. They can't talk about this more as the Argo II is attacked byChrysaor and his crew of dolphin-men. The ship is quickly overwhelmed and Annabeth is captured, with Chrysaor planning on keeping her as a sacrifice to Gaea. Percy turns to Annabeth with advise on how to beat him, but not even Annabeth knows any myths about Chrysaor as there are no myths. When Percy does find a way to outsmart Chrysaor and forces him to retreat, Annabeth gives Percy a kiss and explains that he is brilliant.
Shortly after arriving in Rome, Annabeth plans on leaving to start her own quest alone, but Percy manages to convince her to let him go with her, much to her annoyance. They end up going around the city and seeing some of the sites, eventually stopping at a restaurant for lunch next to the Tiber River. During their lunch, Percy admits to Annabeth that he doesn't want her to go because he missed her and because a they were separated for so long. Annabeth tells Percy that he will have to trust her and to believe that she will come back.
Just then, Tiberinus and his wife, Rhea Silvia, appear and tell Annabeth that they are here to take Annabeth onto the next part of her quest, as they have done for other children of Athena. They force Annabeth and Percy to part once more and take her to the starting point of her quest. Along the way, Rhea talks about the city and how it is changed over the years, all the while praising Tiberinus for his role in the founding of Rome (which he considers to be no big deal). They eventually drop Annabeth off to an underground entrance and give her what little help they can. Annabeth enters the underground and her thoughts quickly turn to her past; mainly thinking about the last time she was truly along was when she ran away from home, before meeting Thalia Grace andLuke Castellan. As she goes deeper, she finds a room with crates of plastic swords and kite strings. Up ahead she finds a large cliff that she needs to climb down to continue onward.
Annabeth quickly becomes frustrated as she thinks about all her friends and how she has watched them all gain amazing powers. She also thinks about how they could use their powers to get down the cliff or gain help in some way, but she has nothing. A voice tells her that she has intelligence, which reminds her that Odysseus had won the Trojan War and defeated monsters with nothing but his wit. Annabeth quickly uses the kite string and plastic swords to make a rope bridge to climb down with. After safely arriving at the bottom, she places the kite string back in her backpack. As she keeps going, she finds herself in a cavern, with skeletons of other Athena children on the floor. Several ghosts appear and declare themselves to be the followers of Mithras. Annabeth looks around and sees that the cavern is decorated with information about their worship of Mithras, including their ranks and the ordeals they must face. The followers of Mithras believe that Annabeth is some form of all knowing entity when she begins to reveal their secrets. This causes unrest in the group, especially when Annabeth guesses that there is another trial besides dying by fire of dagger. Mithras was born from rock, so Annabeth tries to claim that she has passed their trials as she entered the room through a stone entrance. The leader of Mithras' followers says that coming through a stone walkway and being born from stone is different and doesn't count. Annabeth then claims that for doubting her powers, she can destroy the cavern in one strike. When they don't believe her, she uses her knife to hit a weak support beam that causes the cavern to collapse.
During her escape from the collapsing cavern, Annabeth falls and breaks her ankle. When she looks around the room, she finds a few boxes from the Hermes Express, but the boxes only contain bubble-wrap. She initially curse Hermes, but uses the bubble-wrap to make a cast to hold it in place. As she manages to keep going, she finds that the tunnel she came from is filling with spiders. Annabeth is forced to keep going and finds her next challenge; two small beams of wood over a chasm. Despite the beams being to wide and weak to walk across, Annabeth uses the kite string to weave a rope bridge across. Once on the other side, she burns the bridge so the spiders couldn't use it to follower her. Even though they could climb the walls, they don't go any farther down the tunnel. When Annabeth continues on, she eventually finds the Athena Parthenos, but Annabeth is quickly captured by Arachne, who wraps Annabeth in her webbing.
Despite being incredibly afraid of spiders and especially Arachne, Annabeth starts forming a plan. Annabeth starts to complement Arachne on her tapestries, claiming that they are even better than Athena's. Arachne'spride blinds her to Annabeth's plan, and she listens to what the demigods has to say. Annabeth informs Arachne that she is the new architect for Olympus, and would love to feature her work in the main hall. Doing so would also be a huge insult to Athena, something Arachne would love to do. As a test however, Annabeth asks Arachne to make an abstract piece of art that she could show to the Olympians as a type of audition. She shows Arachne a picture on her laptop of Frank's Chinese finger-trap and tells her that it is just what the gods are looking for. Arachne is unsettled as the silk required to make it to Annabeth's dimensions would require more silk then she could make in a year, but Annabeth suggests using the silk covering the Athena statue. Arachne agrees and makes the design perfectly. Annabeth once inspecting it however, informs Arachne that there is a flaw in the middle. When Arachne goes inside to see for herself, the threading becomes tight when she tries to pull herself out, just as Annabeth had planned. Now with Arachne trapped, and the statue uncovered, Annabeth taunts Arachne by saying that she has helped Athena greatly by keeping the statue safe and that it will be featured on Olympus, not Arachne's tapestries. This angers Arachne and she starts thrashing around, causing the floor to crack and fall into the entrance to Tartarus below them.
Just then the Argo II arrives, thanks to some advice from Bacchus, after helping Percy and Jason defeat Otisand Ephialtes. Annabeth and Percy reunite as the rest of the crew start to load the Athena Parthenos onto the ship. As Annabeth starts walking toward the ship, she is pulled backward toward the pit of Tartarus and Percy grabs her, but falls in as well. Unable to cut the thread that Arachne had attached to her ankle, and with no one else able to reach them, Annabeth tells Percy to let her fall so he could save himself. Percy however promised her that they wouldn't be apart again and tells Nico di Angelo to lead the others to the Doors of Death on the mortal side and that him and Annabeth would meet them. Percy lets go and him and Annabeth fall into Tartarus together.
Back on the Argo II, the crew all feel responsible for allowing Annabeth and Percy to fall into Tartarus. However, with some uplifting words from Hazel Levesque, Leo promises that they will save them, even if he has to build a claw that will go all the way to Tartarus.
The House of Hades
Despite the crew of the Argo II trying to reach Greece in order to hopefully meet with Annabeth and Percy, they run into problems. Hazel Levesque feels that without Annabeth there to come up with ideas and without Percy there to motivate them, the crew is slowly falling apart. Annabeth is seen in Tartarus together with Percy Jackson. Along the way, other than coming across Titans from the past, and having the help of Iapetus, Annabeth and Percy come across the arai, who after killed, will result in the killer getting cursed based on the number of monsters they has previously killed. Annabeth was cursed with blindness, from the fact that she killed Polyphemus in the Sea of Monsters, using her invisibility cap and called herself "nobody". As such, before he died, cursed Annabeth with blindness, resulting in her turning blind after killing one of the arai. Another curse Annabeth had was the curse of despair, which caused Annabeth to think that Percy abandoned her, even though he was just next to her. The curse came from Calypso, who felt alone and abandoned after Percy left Ogygia to return to Camp Half-Blood. However, with the help of Bob after she managed to convince him to change his mind, the trio left to meet Damasen, the gentle giant, in order to get Percy healed. With the help of Damasen, Percy is restored to his original condition and get Annabeth's sight restored and the trio are able to continue their journey to the Doors of Death, which are situated in the heart of Tartarus. The dark hills that loomed in Tartarus, reminded Annabeth of her hometown, San Francisco, but just darker. However, in order to reach the Doors of Death, Percy and Annabeth have to seek the help of Akhlys, the Goddess of Misery and Nyx, the goddess of the night. Firstly, they require the help of Akhlys to get the Death Mist, so that they can easily pass through the hoards of monsters present at the Doors of Death without being noticed. They need the help of Nyx, so that they can pass through the Mansion of the Night, in order to get to the Doors of Death.
In order to reach the Mansion of the Night, Annabeth and Percy have to jump three hundred feet into the pitch-black void, which they fortunately succeed. With that, they reach the Doors of Death, which Annabeth describes looks like a heart. Annabeth is shocked to discover that the Doors of Death look exactly like the Mount Olympus elevator doors, just upside down. They figure out that while the other party escapes to the upper world, someone must stay in Tartarus and hold the button to the elevator door for exactly twelve minutes. Then they must cut the chains to prevent Gaea from having the chance to use the Doors of Death ever again. However, unexpectedly, the death mist covering them soon disappears, exposing them to the monsters. They then come face to face with Tartarus himself, who took on a physical form. Both Annabeth and Percy know that they are unable to battle Tartarus, since he is a class by himself. As such, reluctantly but having no choice, Annabeth and Percy enter the Doors of Death, while the Titan, Iapetus and the giant, Damasen, sacrifice their lives to save them. They meet the other five battling demigods in Epirus, and are weak after their time in Tartarus. They then continue their quest to travel to Athens.
The Blood of Olympus
Annabeth and Piper are disguised as Greek serving maidens, with Jason enchanted to appear as an old man by the name of Iros. They are hoping to infiltrate Odysseus' palace, where a "gathering of evil spirits" is taking place. After sneaking into the palace, Annabeth repeats their plans before splitting up from the group. She is seen collecting empty plates and goblets, but when Antinous questions Jason about his purpose among the suitors, Annabeth helps to stall by spilling wine down the ghoul's neck.
When Jason's mother appears, Annabeth informs him that it's only a remnant of Beryl Grace. She later fights the attacking suitors with her drakon-bone sword, taking down many, including Hasdrubal the Carthaginian. Sometime during the fight, Annabeth also received a cut on the side of her neck. She appears at Jason's side when he is stabbed by Michael Varus with an Imperial Gold sword, feeding the wounded boy ambrosia and telling him about Luke's problems with his own mother.
Piper instructs Annabeth to contact Leo through Morse code. She returns saying that Frank will change form and fly Jason up to the Argo II, before crafting a litter that will secure him. When Juno appears, Annabeth coldly addresses the goddess, still bitter at her for wiping Percy's memories and taking him away.
Magnus Chase and the Gods of Asgard
The Sword of Summer
Annabeth along with Fredrick, travels to Boston to look for her cousin Magnus after being informed by her uncle Randolph that he has been missing for two years after the death of his mother Natalie. Annabeth and Fredrick are seen with flyers with Magnus's picture on them, unaware that Magnus himself (now living on the streets) is watching them and overhears them talking about Randolph.
After becoming an einherji (due to dying in battle against the fire giant Surt), Magnus returns to Midgard and goes to the funeral home his old body is being kept, in order to look for Sumarbrander (the sword he died with) where he meets Annabeth who promises not to tell anyone she saw him. Afterwards, Annabeth gives Magnus her phone number to contact her to which he agrees.
The two meet up at the Blue Hills to scatter Natalie's ashes.
The Hammer of Thor
Magnus mentions that Annabeth told him about the Greek Gods.
The Ship of the Dead
Annabeth appears in the beginning of the book with Percy. Percy trains Magnus with ships and water then he and Annabeth drive away in his step-father, Paul's, Prius.
- As revealed in The Lighting Thief, when she was younger, Annabeth had a pet Doberman, which she took to obedience school. She later used the lessons from obedience school to tame Cerberus when she, Percy and Grover arrived at the Underworld.
