lots of unexpected twists and turns at the end (as well as a few things that were easily foreseen). All in all an excellent book.
Only thing I questioned was they're struggling to survive and most of the other countries were wastelands(assuming I didn't misread something), so why were the surviving nations still so concerned about CO2 emissions (from coal). Possibly a way to control the population? His short stories appear to be set in the same universe, perhaps one of them might explain it.
I checked out his site today and this book and Pump Six and Other Stories are available on DRM-free ebooks. PSOS is apparently sold out and won't be released in paperback until the end of the year.
