A good friend of mine started a book club not too long ago. When I asked her about the first meeting she said "I hate it. Everyone is fighting and they all want to do books where they learn something. I'm not going anymore."
"But you're the founder!" I said "Don't you have to go?" But there was no persuading her. "I just want to read good books." she said, "not listen to nonsense."
Their best option as far as I could see, would be to pick a Laurie Graham book. Good (so good!) with the side effect (particularly with her historical fiction) of learning something. I'm rereading The Liars Daughter at the moment and it is so interesting and crucially, a really enjoyable read.
