Yes, another Avengers and Percy Jackson crossover with good ol uncle Tony. Cliche I know. Peter Parker was finally given something to do, a mission sorta. He had to go to Goode High school for a while to gather intel on Percy Jackson, who was deemed suspicious by The Avengers due to his strange record of disappearances and damaging property, but then files that say he didn't. So he becomes friends with Percy and finds out a lot, and realizes that Percy is actually innocent. The Avengers decide that they should confront him themselves and ask him to go with them for questioning. Little did they know Percy didn't like that idea. Join Peter Parker and Percy Jackson on their adventure, kinda, but not really, while they discover the other persons secrets. I don't own these characters, they belong to Marvel and Rick Riordan.
