Changing of the Tide - PJO YJ crossover
Percy has lost everything, the Fates really must hate her. She's lost more people than anyone, and, she blames herself. She blames herself for the deaths of the seven, for everyone in both camps being dead, heck, even for the last war. She's drowning in survivors guilt and depression. Her name is Persephone Andromedea Jackson, and she is the last demigod on the planet.
The Fates make a deal, to bring back all those who weren't supposed to die, but there's a catch. Percy must join YJ, and try to remember/ find her family.
