I was so looking forward to this book. The first book in this series, "Rot and Ruin", won my heart with its unique outlook on zombies. The second book, "Dust and Decay", further developed the characters and made me grow to love them. The third book, "Flesh and Bone", was amazing with its crazy zealots and religious wars. That being said, this final book just did not live up to its potential for me. It took entirely too long to pick up and it often felt like absolutely nothing was happening for hundreds of pages. The zealots are still present (and are by far the most interesting part of the entire book), but their creepiness is just not enough to save the story overall. This book was good, but when you compare it to the others in the series, it falls very flat. I'm sad the series is over, but a part of me is also glad. This story and its characters have simply run their course, it is time to let them go and move on to something else. I would recommend this book to anyone who has read the previous books in the series, simply for closure and completing the overall story. (But I warn you, be prepared to wade through a LOT of filler just to get to the end of this one. The pages will not fly by as they did in previous books in the series.) I'd also recommend this to fans of zombie novels with a scientific and religious focus, since Maberry is very skilled at incorporating both topics seamlessly throughout his tales.
