I suggested a sci-fi short story collection once, and we also listened to the podcast series The Witch Trials of J.K. Rowling once (several of our group almost exclusively read audio books anyway). Both inspired a LOT of discussion. Also fun was when half the group read Americana: A 400 Year History of American Capitalism by Bhu Srinivasan rather than Americanah: A Novel by Chimamanda Ngozi Adichie.
What's something your group has read that felt outside the usual?
