One rainy morning in June, two years after the end of World War II, a minor traffic accident brings together Eleanor Moskowitz and Patricia Bellamy. Their encounter seems fated: Eleanor, a teacher and recent Vassar graduate, needs a job. Patricia's difficult thirteen-year-old daughter Margaux, recovering from polio, needs a private tutor. Invited to keep Margaux company at the Bellamys' country home in a small town in Connecticut, Eleanor meets Patricia's unreliable, bohemian brother, Tom, recently returned from Europe. The spark between Eleanor and Tom is instant and intense. Flushed with new romance and increasingly attached to her young pupil, Eleanor begins to feel more comfortable with Patricia and much of the world she inhabits. As the summer wears on, the two women's friendship grows--until one hot summer evening, a line is crossed, and both Eleanor and Patricia will have to make important decisions--choices that will reverberate through their lives.
