Annabeth Chase

Annabeth Chase is a demigod daughter of the Greek goddess Athena and girlfriend of Percy Jackson. She is one of the main protagonists in Percy Jackson and the Olympians and The Heroes of Olympus. She appears in The Staff of Serapis and meets Sadie Kane.

Background
Annabeth's father, Frederick Chase, fell in love with Athena when she helped him with his classes at Harvard University. In 1993, Athena sent him Annabeth as a gift, she was wrapped around with blankets in a golden basket. When Annabeth was 7 years old, monsters began attacking her family, which now included a stepmother and two stepbrothers. Annabeth's stepmother opposed her and called her a monster. She ran away from home and teamed up with Luke Castellan and Thalia Grace before going to Camp Half-Blood.

The Son of Sobek

 * Percy mentions Annabeth to Carter. Soon, Carter wonders who Annabeth is, later in The Son of Sobek.

The Staff of Serapis

 * After failing an interview, Annabeth is going to the subway to go to Percy's apartment to cheer her up. Suddenly she sees a monster with a wolf and a lion head sticking out of a cone shaped shell. The monster glares at her, and then turns away, as if it has business elsewhere. Annabeth decides to follow the monster, as they normally do not leave demigods like her alone. After this she realizes she doesn't have her knife so she starts making the heads argue with each other.  A train pulls in and Sadie does a few spells on the monster. The monster starts running away and Annabeth and Sadie introduce themselves. Sadie also has a dog that just appeared in her library that she named "Fido". She asks Annabeth to come walk her dog with her, and they exchange strories, both of them finding out about the other's world. Annabeth also remembers Percy recalling fighting a giant crocadile with Carter. Sadie however, didn't know that and said she'd confront Carter later. Fido then breaks loose and both Sadie and Annabeth are blown backwards. Annabeth picks up Sadie's wand and it turns into a dagger, and Sadie tells her to keep it. She then realizes that Fido was heading straight for the "storm". Annabeth doesn't know what she means until Sadie rubbed some pink goop on her eyes so she could see into the Duat.  They then head after Fido, but arrive too late because he merges with the rest of the staff. They then realize that they see a man on top of the building. They start figuring out this monster and this man (god) were both Egyptian and Greek from the time when Ptolomy was the pharoh. The structure of the building is also changing. Sadie says that they'll split up and that Annabeth could deal with the god that they couldn't remember the name of with her staff creating a forcefield around her. He keeps ignoring her untill she figures the god's name and yells "SERAPIS".  Once she gets Serapis' attention she starts talking to him trying to give Sadie enough time "to do whatever Sadie was going to do". She saw that Her friend was drawing chalk circles, and once they were complete she said the spell "tyet" and then said the "ha di" spell. However Serapis just waved it away like it was a fly. When that didn't work she yells "Suh Fah!" and the entire wall collapsed on him. (Suh Fah was a loosening spell.) They get off the building, but then see Serapis again. Annabeth tells Sadie what she learned from talking to him, he was building a new light house of Alexandria, he wanted all the gods to come to it so he could destroy them, etc.  They then form a new plan to get rid of Serapis because he emerges from the rubble. Annabeth teaches Sadie some Greek and she starts chanting Egyptian and Greek to confuse Serapis. Then Annabeth with the invisibilty hat on she destroys the dog head, representing the future on Serapis's staff. (There are three heads on the staff) Serapis than is vanquished, and Saidie tells Annabeth abut her speculations that Setne was the one who released the Son of Sobek and Serapis. Sadie and Annabeth exchange phone numbers and part ways.
