November Book Club will meet after church, November 26 to discuss C.S. Lewis' The Screwtape Letters.  This was one of the closest votes yet, with two of the books just behind. I suspect we will take up one of the other nominees in future months.
You can find The Screwtape Letters in many different formats. It has gone through several printings and has a number of audiobook options, ranging from John Cleese to Andy Serkis. (Do watch on the audio versions that some are abridged.)
I would love to join the group for this discussion however I will probably be in Chicago visiting the kiddos.
