Clique.
Another predictable YA novel with a selfish girl as the protagonist who wants more than she is given and doesn't care who she hurts/kills in the process. Throw in stupid love triangles and whatever subject is selling the most books (this time zombies) along with some religious zealots (no book is complete without it!) and you've got yourself a "best seller".
Sad thing is the movie is probably coming out next month. Sigh...
