A few days after the giant war, Percy is alone in the world. A week out of Tartarus, EVERYONE is gone... all because of Gaia. Now a group of "super heroes" want Percy, but he wants to be left alone. There's something big coming, something that only two people have seen, but three have experienced. Only one is still alive... He's coming and he's after something. Or Someone... Avengers assemble to try and detain a certain half blood. No records of him, just his name, age, parents(deceased), a few notes, and a photo from about 9 months ago. Who is Percy Jackson?
