Percy has just returned from the Giant War, and things are going well. Sure, he's still haunted by the occasional nightmare regarding his time in Tartarus, but he's getting better. Things are finally starting to go his way. He's even starting at a new school for his senior year: Midtown High.
At school, Percy becomes good friends with Peter Parker, a strange but kind (not to mention extremely smart) kid in his grade. Each knows the other is hiding something, but neither boy wants to expose their secret. There's a looming threat facing the city, though, and the two of them are going to eventually have to work together somehow if they want to stop this thing.
Notes: This takes place after Homecoming (so May knows about Peter being Spider-Man), but I'm ignoring Infinity War and Endgame for the sake of the story). Also, there's occasional profanity, but it's not too frequent!
