ONE PERCY

DON'T READ THIS IF YOU HAVEN'T ALREADY READ PERCY JACKSON AND THE OLYMPIANS, THE HEROES OF OLYMPUS, AND HARRY POTTER!!!
Percy Jackson loses his memory. Again. He is being attacked by people with weird tattoos. He soon gets a letter telling him to go to Hogwarts. He finds Annabeth and Reyna there, and they're the oldest first years in the history of Hogwarts.

And there are two missing students.

Luna Lovegood and Hermione Granger.

Watching the movies does NOT COUNT as reading the books!

(But I'm not the boss of you of course so feel free to ignore all of this)
