I had high expectations for this book because I loved Anna Dressed in Blood. I wasn't even half way done with it and I couldn't stand Cas. He was super whiny in this book about Anna going to hell and wouldn't stop about it. I can stand a little whinnying but his was nonstop and such a total change from the 1st book. In the first book he was kind of cocky, strong and confident and this book I didn't like him at all. 
 I couldn't find a third book in this series so I'm not sure if there is going to be one or not. I would probably read it even if this was not the last one.
