I am a total sucker for postapocalyptic stories, and this one brings the dysfunction in spades. I can't wait to see how it ends!
Caveat: I wish I had known going in that this is the first book in a planned trilogy---the pacing and ending would have made more sense. The book does do very well at creating a sense of impending doom, and the immediate aftermath is portrayed well. It's just a bit uneven, and then it just stops, rather than ends. Now I'll have to read the trilogy to judge this one fairly. Oh, darn.
