The Rules of Engagement — Anita Brookner

Elizabeth and Betsy had been school friends in 1950s London. Elizabeth, prudent and introspective, values social propriety. Betsy, raised by a spinster aunt, is open, trusting, and desperate for affection. After growing up and going their separate ways, the two women reconnect later in life. Elizabeth has married kind but tedious Digby, while Betsy is still searching for love and belonging. In this deeply perceptive story, Anita Brookner brilliantly charts the resilience of a friendship tested by alienation and by jealousy over a man who seems to offer the promise of escape.
