I enjoyed this book,although I'm not entirely sure I would have picked it up on my own had I known now about the plot. Which may be the point.
Spoilers from here on out.
I thought Carey did a really good job with the post-zombie-apocalypse element and his take on what happens next was intriguing. It was clever in a way that zombie novels aren't always clever and surprisingly compelling in both character and narrative. It was really good.
