If I may make a suggestion: It seems unlikely that the November selection will be both picked and read in time to comment on it in November (especially with the holiday season coming up), so why not make it either the December or January pick and, in the meantime, make suggestions enough to pick twelve books (or even six) for next year? This would give people enough advance notice to have a better chance at actually reading the book rather than having to rush through or skim it if they wanted to participate... and that way there'd be a better discussion for that month.
Also, I suggest that whoever heads the club be someone who can commit to it, if you want it to succeed; and that would mean a fair amount of time spent in this, as it will entail collating all the selections, putting together a poll for voting on them, etc., as well as keeping up with when the next batch of titles needs to be chosen.
