The Good Sister Fern Castle works in her local library. She has dinner with her twin sister Rose three nights a week. And she avoids crowds, bright lights and loud noises as much as possible. Fern has a carefully structured life and disrupting her routine can be . . . dangerous. The Mother-in-Law From the moment Lucy met her husband’s mother, she knew she wasn’t the wife Diana had envisioned for her perfect son. Exquisitely polite, friendly, and always generous, Diana nonetheless kept Lucy at arm’s length despite her desperate attempts to win her over. And as a pillar in the community. The Family Next Door From the outside, Essie’s life looks a loving husband, a beautiful house in a good neighborhood, and a nearby mother who dotes on her grandchildren. But few of Essie’s friends know her secret that in a moment of maternal despair, she once walked away from her newborn, asleep in her carriage in a park.
