The first rule of book club is that you don’t talk about book club.
The second rule of book club is that you have to bring a book suggestion for the next book club.
In all seriousness, though, my local atheist book club us reading R.A. Lafferty now, and it’s a strange trip. Here is the best recommendation I’ve yet seen:
There was a writer from Tulsa, Oklahoma (he died in 2002), who was, for a little while in the late 1960s and early 1970s, the best short story writer in the world. His name was R. A. Lafferty, and his stories were unclassifiable and odd and inimitable — you knew you were reading a Lafferty story within a sentence.
Neil Gaiman, Introduction to Fragile Things: Short Fictions and Wonders by Neil Gaiman. published 2006 by William Morrow. (Pg. xxvii)
If you trust Gaiman’s judgement, there is a freely available collection of Lafferty short stories here. Share and enjoy!
