Percy Jackson Daughter of Kronos

Percy had a job to do. A big job, all he had to do was save Olympus but he failed. With his failure came the defeat of the gods by Kronos. Yet that wasn't it. It wasn't over, Percy was offered help, a chance. A chance to do better, to go back and change things. He wasn't able to save his world, can't change anything but possibly going back to the beginning SHE can. Fem/Percy F/F
