We laughed about it, and then I thought about some of the other novels that moms and daughters may have shared without discussion. My list is limited to women's fiction published since the 1950s.
The first one that comes to mind is Grace Metalious’s “Peyton Place,” which was published in 1956. I vaguely recall my mother and some of her friends discussing the novel (but not in front of me).
In the 1960s, it was Harold Robbins’s “The Carpetbaggers” (1961) Jacqueline Susann’s “Valley of the Dolls” (1966), and Irving wallace's "The Seven Minutes" (1969).
The 1970s had Erica Jong’s “Fear of Flying” (1973), Susann's "Once Is Not Enough" (1973) and Judy Blume’s “Forever…” (1975).
From that point on, practically everything imaginable has found its way into print -- right up to the "Fifty Shades" trilogy.
