I really wanted to like this book. Its got zombies and a dystopian element to it and normally I love zombies and I love dystopian fiction. I think the big problem is that I HATED Mary. I spent the first half of the book questioning her sanity and whether or not some of the events were really happening at all. She was selfish and whiny and I'd say 80% of the book was her internal monologue.
However, that being said, I did find myself interested enough in the plot to finish it... to find out where the author was taking us.
