All of them gone. even Annabeth, who had survived torture in hell with him. As punishment, He is cursed with a type of immortality. He can only die when they feel he has repaid his crimes. The gods send him back in time to live out the past. Take the slow road. Percy disowns his name. Going only by the first part of his last name..Jack. Centuries pass and he becomes known as Jack Frost. Now, time has finally brought him back to where he belongs. A year where all his friends and family are alive..and he's nowhere near them.
