The Pursuit for Annabeth Chase

They won't tell me exactly what happened. I hear whispers behind doors. A freak accident—a catastrophe. I was rushed to the ER. The doctors didn't expect me to survive. But I have, and now I have no memory of my former life. But I have a mission: to find out everything I did, the person I once was. What puzzles me is why the new boy, Percy Jackson, wants to help me with it. AU, AH.
