Notes from a Big Country by Bill Bryson
Bryson's classed as a Travel writer, but he really is so much more. This is a collection of articles (although un-distinguishable from chapters thanks to his writing style) he did on moving back to America after a period of living in Britain. Very funny, informative, but not simply observational stuff. I think it'd be a different choice, and maybe not ideal for the first book the club covers. Definately worth considering for a change of pace from fiction though.
