The Godslayers

Jay woke up in Hell.
It wasn't because he died. In front of him is a set of stairs that'll take him to the surface. He soon realizes that he possesses strange powers from the ancient Greek deities. That's not all: eleven other kids have their own abilities, though they're not using them to protect these higher beings.
Like the Giants before him, these kids are part of a bigger fight, and the outcome will determine the end for one side.
They're here to end the reign of the gods once and for all.
