/Rewritten summary/title/ What happens at Hogwarts on a regular day is, to put it lightly, strange. But add demigods, birdkids, birdkids who are demigods, and a whole lot of confusion, and what do you get? Something a little more than strange. (New title, title was previously Percy J and Max Ride at Hogwarts!) Maximum Ride, Percy Jackson and Harry Potter crossover.
