Good, quick read, but I was slightly dissapointed. I expected this book to be scary, maybe I am just desensitized because I didn't think it was scary at all. I'm not upset about this, however because I almost didn't read it because I don't really care for horror movies or anything really that makes me scared. I thought the book was based on a great idea, the writing was good, I just didn't connect with the characters the way I would have wanted to. I didn't get why Cas was in love with Anna either because they didn't interact enough to develop those types of feelings. I would have liked more back story on the thing that killed Cas's dad and more from the character of Anna. Overall, it was an easy read but I don't think I will pick up the sequel, not enough here to keep me interested.
