The Fallen Angel
Percy Jackson isn't a son of Poseidon. Hell, he isn't even a normal demigod. His father is Zeus, Lord of the Skies and King of Olympus. While that seems normal, (for a demigod) he is also the son of Jupiter. He is a child forbidden to even be alive. As a child of both Greece and Rome, Percy Jackson is not allowed at either camp. His father decides to take a chance at letting him live in the mortal world, away from the dangers he might encounter in the mythological world. He is raised by Zeus himself, in a way that doesn't go against the ancient laws. Zeus has his immortal son, Ares, train the boy from the moment he can stand. Now as the threat of Kronos rises, Percy must be the child of the Prophecy. Will this demigod be what it takes to destroy Kronos and his army or will they end him before he gets the chance?
