Percy Jackson has a family that not a lot of people know about even Annabeth. What will happen when he finds out his parents are dead and that the police won't let him live with his Aunt because she does a lot of under cover work? What happens when he finds out his mom had a brother that he never knew or met? Yes this is a Percy Jackson and Avengers crossover. *Disclaimer* I do not own any of the characters. I only own the plot.
