The ruins of New York City are described in compelling detail, with familiar sights and locations sprinkled throughout. I had a clear picture of where everyone was and what it looked like. Unlike other books in this genre, I liked how organized these survivors had gotten and how well they seemed to get along and help each other. The survivors Noah meets away from the safety of the organized groups were scary and surprisingly creepy to me. I can't get that couple he encountered in the restaurant out of my mind.
