Each time there is another violent protest or shooting, what comes to my mind is The Good Mother.

That’s the 1986 novel by Sue Miller about a woman, recently divorced and raising her three-year-old daughter alone, who tumbles into a sexual idyll so magical and all-consuming that she lets down her guard. In her zeal to reshape her life, she allows something to happen that gives her resentful ex-husband leverage, and, to the outside world, the appearance of righteousness.
