Sorry for running late on this one... Please drop some book club nominations for October (preferably not 1000 pages as we are getting started a little late).
Since it's spooky season I'll nominate John Dies at The End by Jason Pargin. It's an awesome horror/sci-fi with a sharp sense of humor.
I second John Dies At The End. You may find it under the pen name "David Wong". Amazing book and a really great movie adaptation, IMO as someone who watched the movie first.
