Overall the story was good and the relationships between the characters developed nicely. I don't know why, but I'm always a sucker for the stories of what happened to each individual during the crisis or the turn, and I really enjoyed those sections.
I only gave the book 4 stars because I was sometimes confused by who Nina was supposed to be. The character seemed to waiver a little bit from when the book first started out until she finally found her flow about half-way through. Even though that development part was a little shaky, it shouldn't stop anyone from picking this book up, especially those that love some good old-fashioned zombie fic.
Claire C. Riley is definitely on my watch list now!
