Until she was found dead along the bank of the Hudson River, Molly Marx led an enviable life. A young wife and mother, Molly now finds herself in the Duration, where with the help of a refreshingly unorthodox guide, she can observe the friends and family she left behind. She observes her philandering plastic surgeon husband, the irresistible colleague who became her lover, a competitive twin sister, her controlling mother-in-law, a loyal but confused friend, and her purest love: a three-year-old daughter.
