Betrayed - P.C. Cast & Kristin Cast - paperback

House of Night series, book 2 of  12 completed series

All any of us could talk about was Chris's disappearance and how bizarre it was that he had lasxt been seen so close to the House of Night. I didn't want to believe it. But everything inside me said that the kid would be found, but he'd be found dead. 

Things seem to be going pretty well for Zoey Redbird. She's settled in at the House of Night finishing school and is coming to terms with her incredible new powers. It all seems too good to be true. And guess what? 

Someone has begun murdering human teenagers, and all evidence points to the vampyres at Zoey's school. Which means her first assignment as the leader of the Dark Daughters is finding out which one of her classmates or, gulp, teachers is a killer.

Sigh. And she thought her boyfriends (yes: plural) were going to be her biggest problem this year.
