Christina Simon writes: “Everyone in L.A. seemed to be in a book club, except me. I’ve never been invited to join one and every time I asked friends about their clubs, I was met with responses like ‘We’re full,’ or ‘It’s only moms from our school.’ Once a friend told me her book club was ‘the absolute best,’ but when I asked if they had openings, she told me, ‘I’ll give you the name of our moderator so you can start your own.’ This reinforced my suspicion that book clubs were mysterious get-togethers for social types—and I didn’t fit the part.”
