I'm fairly sure I bought this book after a Book Riot post of the best books of 2014. It has zombies in it, which pretty much goes right along with my current delight with zombie books. I've been lucky so far to have read some good zombie books (World War Z, and Mira Grant's Feed trilogy), and this one continues that trend.
The beginning of the book is odd, and I struggled to follow along but briefly. Once I relaxed into the story, it read very quickly. I really like the explanation of the cause of zombie-ism (new word, totally correct), along with the consequences of the continued existence and development of said cause. The social fallout of a post-apocalyptic zombie world is also well portrayed, with different levels of coping with the end of the world (as we know it).
The ending was satisfying, with pretty much the only way the zombie world could continue (given the parameters of zombie-ism provided).
I enjoyed this book and recommend it if you like the zombie fiction genre.
