Jen and Isla have nothing in common - except their love for the same man. Isla is Richard's wife of ten years: they make a handsome, gifted and admired couple. Jen has been his mistress for nearly as long: with her he is someone else entirely. When a chance meeting brings the two women together, each is forced to re-evaluate the man she thought she knew. But after the initial shock subsides, they begin an enduring friendship that survives the worst tragedy either can imagine: Richard's premature death.
