Four days after Percy reported Annabeth's death, Percy himself went missing. Everyone assumed mystery girl had killed him, or he ended his life himself, so a funeral was thrown for him. Everyone had a word to say about Percy Jackson, the hero of Olympus. What no one knew was that Percy was watching his funeral, standing by the side of a black haired dark skinned girl. She whisked him away afterward, and no one heard from her again until six years later. 

Dear campers,
I am here to bring you some sad news - Percy Jackson died last night. Shocker, I know. He didn't die six years ago. He has been with me this entire time, nothing but a shell of a human being. I slit his throat, and I know he was glad for it. Now I'm writing to tell you, that I won't be bothering you anymore. You'll never hear from me again. My revenge has been completed and there is nothing left for me in this world. Farewell, campers. But before that happens, I'm going to let you in on a secret - I'm not evil. Love can make someone do crazy things, you know? Something you might want to stay away from if you don't want to do something crazy for love and be called the scum of Kronos' shoe.
