Book Club Reads??

I belong to a book club made up of teachers. We do actually read and discuss books, but most of our time is spent discussing education and various things going on in our lives related to this. When we started out, we would actively try and discuss the book. Our format is to read the first half and meet, then finish and meet again. Now we spend maybe 10 minutes of our 2 hour meets on the book. Don't get me wrong, it is nice to vent to my friends and we all need it. But we have also discussed the fact that we need better discussion books. So I ask you: what are some books you would recommend? Preferably not education related, as we get enough of that in our daily lives, and because our meets always end back on that topic anyways. Thanks!
