I was thoroughly entertained. Sure it may not be that unique, but post apocalyptic stories with monsters are always fun. Trying to survive in a world where human morality becomes thin, trying to figure out who can be trusted or not are always intriguing.
I liked Amy and Baby's relationship. Though they may not be blood, there connection is thicker. I found their communication system cool, especially how they modified it.
The twist can be easily predicted. I'm so psyched for the next book! Leaving a brain washed psychotic leader community to a no law zoo fest! Out of the frying pan and into the fire! Though the latter place sounds less safe, but at least there are no stab in the back secrets. More honest brutality, more freedom.
Usually these books go opposite direction s, but I like how this goes from finding out the truth firsthand.
