The most boring, uninspiring, zombie and/or post-apocalyptic book I have ever yawned through. 
 I just looked down and saw this had sequels, so that makes the abrupt, pointless ending a little more forgiveable. 
 However, the characters were shallow (the guys were all more interesting than the girls too), no one was very bad or very good, all mediocre. It seems the author just wanted to write about the zombie apocalypse, and she never thought about the depth nor purpose of her world. You can get away with it in a movie, but not a novel. 
 If you like zombies, read ROT and RUIN instead, it's worlds beyond "The Forest of Hands and Teeth."
