Loved this book! I was in the mood for some zombies, and this book definitely had them! I don't really know how to review this book, but here are some points about it:1. Littlefield's writing definitely got some getting used to- but once I did, I couldn't stop reading. It flowed so beautifully that I felt like I was IN the story.2. I would get really paranoid thinking a "Beater" was going to come attack me whenever I was alone... (even in my house LOL) Such a believable world.3. Cass is an awesome character. I love that her flaws outweighed everything else about her. It just made her seem so much more real.4. The only thing I didn't like about this book was that at points it seemed to drag on. I'd find myself taking long breaks while reading because some parts could get semi-boring, but things usually picked up pretty quickly.
