Warriors of New York (PJO x Avengers)
16 parts Ongoing (Takes place after Trials of Apollo and the avengers movie)
After Nico and Will let Percy and Annabeth know about their new and dangerous quests, they are understandably worried. Percy thought college life was hard enough without your friends going on the most dangerous quest possible. And boy is college hard. Why did Percy choose to study marine biology! The math, the memorization, the fancy science words! It all feels like too much sometimes! Why can't we just call every fish Nemo 1, Nemo 2, and so on and so forth?
And yet, Percy also couldn't be happier. He is finally going to college with Annabeth, his dream ever since they became an official couple. And most importantly, he's alive and (mostly) well. Do dreams of the pit still plague him to this day? Yes. But he and Annabeth can face anything as long as they're together. (And the local New Rome therapist doesn't hurt either).
But (as usual) one phone changes everything. When Sally Blofis calls in absolute panic saying people have broken in and she's being kidnapped, he has no choice but get her back as soon as possible. And the only way to do that is to team up with the (second) greatest team there is: The Avengers.
