A girl named Cara gets thrown into a bunch of different worlds (because what's better than that?) and eventually starts to mess things up.
During Casey's (and the marauders) third year at Hogwarts, it starts to become clear that Remus Lupin is a werewolf, and the main character starts to figure it out as the marauders figure it out.
I wrote this (amazing?) piece of work while in the seventh grade. This is my guess on what would happen if my friends and I were in the series of The Lord of the Rings. The next part is for the Hobbit.
