A book club can be whatever its members want it to be. If your group is happy to chat about the book for 15 minutes and then move on to dissecting recent events on Real Housewives of Atlanta, that’s completely fine. If your members actually want to read all of Jack Kerouac’s books and discuss them, at length, with no interruptions for gossip, wine or toilet breaks, that’s fine, too (although I will not be joining).
