Pros: I was really intrigued by the concept of female (and thus human) extinction by some unknown cause. The characters and events that took place within the compound were compelling and interesting to read. Cons: The latter part of the story seemed to drag a bit, and wasn't as fluid as the beginning. Also, one of the most likable characters dies, which was very disappointing. Overall, a decent read. I hope the rest of the series is better though!
