Percy Jackson wakes up in a cold sweat, certain that Annabeth hated him, certain that the gods had thrown him into Tartarus because he was apparently 'too strong to live', certain that his head had been dislodged from his neck by Kronos, but thinks it was all a dream...until he finds that he is no longer at Cabin Three. He has a bit of trouble, but soon recognizes this place as...Yancy Academy?
Percy Jackson soon finds that he had been granted the power never to die and always repeat his life from a certain point, and decides to use the power to his advantage.
But, the bigger question is...who is helping him, and why?
