This is the first zombie book I have read and I really enjoyed it. I loved how the book showed how crazy people can get AFTERTIME. It seemed like one extreme way of survival to another with the Rebuilders, the Box, and the Convent. Everything was so nasty, gritty, and intense but seemed so realistic if put in that situation. I look forward to reading the next book and learning more about Cass, Smoke, and Dor.
