I was up all night with this one. Gripping, intense, realistic dystopian fiction. A few plot points strained my credulity some, but overall it's taut and involving. Sympathetic characters are finely drawn and their struggles adjusting to the post-asteroid-struck-moon world are eminently believable. It was also nice to read an end-of-the-world book set in a small town- I can't remember a really good one since Alas, Babylon. Highly recommended.
