There were some left out words throughout the whole book that were rather noticable to me. The book overall was kind of disappoiting to me. I am a huge zombie book fan and have read plenty and this one just left me wondering why the heck I got it in the first place. I'm guessing there is another book after this one because the way it ended was just stupid. A chapter or two just kind of were stuck in there (although in the end you find out why). Overall, it wasn't a terrible book. It just wouldn't be worth paying for at a bookstore...to me at least.
