One other idea is to alternate between a work of fiction and a work of non-fiction. That way, we can appeal to a wider audience.
Do we want to try only books that have both a print and audible version to be the most accomodating to members?
Both ideas sound fair. I'm a slow reader as well but I'll try my hardest to finish whatever book we decide on. The reason I'm a slow reader might be because I'm alternating between two books at the moment, not including my emergency book I keep at work (in case I forget my other books at home and have nothing to read. ;D)
