I've read several zompoc books. This is different in my opinion. The lead has a cool sense of humor. She's easy to like. Also, she literally has to eat brains so it skirts the edge of gross sometimes, but that really adds to plot for me. It doesn't take things too far in the horror or gore direction, but it gives enough to make things interesting. There are people being killed, and she has no idea how she became a zombie. There's mystery, action, comedy and an engaging storyline.
