After the Giant War Percy is hoping to have a normal life, well as normal as it can be when you're a half blood. He plans to finish the school year in New York and then head to Camp Jupiter with Annabeth and all of his friends. But his plans change when the gods make him go to Beacon Hills, where there could be a threat of new and dangerous monsters. While there he befriends Scott McCall and Beacon Hills is not as quiet as Percy first thought.
Set after the Giant War and before Season 5 (I know that Season 5 has started and it starts off on like the first couple days of senior year but I'm gonna pretend that all of that stuff hasn't happened yet but it will happen after Percy leaves and my story ends).
Disclaimer: I don't own the Percy Jackson series or Teen Wolf no matter how much I wish I do.
