Misplaced. (A House of Night [fan] novel.)

After calling up her Aunt Trish she's sent to the House of Night where her room (and roommate) await her. But when High Priestess, Alah, makes a mistake and Cam is accidentally set to live in the boys dorm and there's no other option, Cameron is forced to share a room with a male fledging she doesn't even know. Not to mention he's insanely hot...with an ex-girlfriend who's the most horrible girl at the House of Night, and will stop at nothing to make Cameron's life a living hell and get back what is 'rightfully her's'.
