Just finished a book called Liminal States. First novel by Zack Parsons. It's a dark 19th century western, a hard-boiled detective story, and a totally $#@!ed up dystopian alternate history / sci-fi all rolled into one. Well written and nightmarishly creepy.
It was pimped on boingboing -- I don't know anyone else who's read it, but I enjoyed it. A lot.
Also if you never look at boingboing I recommend it. They make good sci-fi type from time to time, and generally advance the cultural conversation, IMO.
