She's really gone.. Percy Jackson is not your everyday demigod. Son of Posideion and all ya know. Percy can breath under water. sometimes it's a blessing. other times..not so much. Annabeth Chase the smartest demigod of the century. She is gone. Annabeth Chase is dead. She 'commited suicide' while Percy was at his mom's. She drowned. What She knows she passes to Nico who tells Percy. Then Percy snaps.
