OK, I'll play, too, and expand my post and up my stats a bit, as I only included books where I participated in the discussion and not total read, i.e., the books that I didn't reread because they were too long or because I didn't like them enough. In a few cases, I didn't reread, but remembered the book well enough to discuss it anyway.
2015 - I read and discussed six of eight so far. I mentioned especially enjoying
Our Man in Havana and
The Age of Innocence, which was a reread and so good I upped my stars to five at GR as a result.
West with the Night and
Cannery Row were rereads that I still didn't like much.
2014 - I read seven of twelve, but didn't reread/discuss
The Grapes of Wrath (not a Steinbeck fan, see above and unlike
Cannery Row, it's long). Several others were rereads; new to me was
On the Trail of Genghis Khan and it was one of my books-of-the-year.
2013 - I read nine of twelve, but it was kind of a dud year. A reread of
Persuasion is always lovely, but dreadful books included
A Town Like Alice (I didn't reread this, but remembered it well enough to discuss, no doubt because of my loathing.),
Dr. Izard and
20,000 Leagues under the Sea. I think this is why my participation was down the next year.
2012 - I read ten of twelve, which includes several rereads. The good:
Tender is the Night (my single favorite book with the club). The bad:
Shutter Island and
Cloud Atlas. The latter really surprised me, as I had loved
The Thousand Autumns of Jacob de Zoet by the same author.
2011 - I read nine of twelve, including rereads. Best new-to-me was
The Island of Dr. Moreau; no real duds that year. (I was lucky; I knew
Hal Spacejock wasn't for me so I didn't even try.

)
That brings me up to 41 out of 56, of which I discussed 35.
