Not every book is worth discussing. You might be reading a highly engaging book, but when it comes down to really talking about it, there's not much there. This  happened to our group when we read "The Pilot's Wife" by Anita Shreve. Sure, it was a good read. But there wasn't much depth. There were no jumping-off points for the literary back-and-forth we were used to enjoying. Our discussion went something like this: "I liked it" and "I liked it, too" and "So did I" and "Well, I didn't like it so much." On the other hand, when we discussed "Makes Me Wanna Holler" by Nathan McCall, our discussion was lively and, at times, heated. Our group was made up of women of various ages from different parts of the country with diverse views about class and race and opportunities. We had a lot to talk about. It was a great night!Now, this is the same book group with two very different kinds of discussions. What made the difference? Vetting.With "The Pilot's Wife," we broke one of our rules. We always require that at least two people read the book and recommend it. We need to know that it will be worth discussing. Generally two people can come to this conclusion or not. It's a good safety measure if you want to make sure your discussions are satisfying and interesting.
