This dystopian novel has an interesting social commentary. It reminded me of the story of Moses leading his people to the desert. The character number-names were a unique and interesting idea, but took me out of the story at times as I tried to keep everyone straight. There was a lot of reassurance in how it turns out for one character, who proudly uses his name in a mental declaration three-quarters of the way in-- that was my favorite part. (He wasn't a .... he was a ... and that was just fine.) I wondered, as he did, why a certain group didn't go elsewhere. Their reason for staying seems flimsy-- but that's exactly the way people seem to be about not leaving an area, even when things are bad.
