Upstate — Sallie Bingham

A woman's obsession drives an affair out of control, violating social contracts and devastating the people in its path. For years, Ann and David shared weekends and holidays with country friends Flora and Edwin, even after womanizing Edwin took Ann away to pick grapes and started a year-long affair. The ground rules were clear from the start: Flora accepted what she called Edwin's meaningless “things,” and Edwin stipulated no divorces. But Ann's empty marriage (to which David was providing neither money nor sex) and growing need for Edwin causes her to ask for more, leading to estrangement and a startling climax.
