It came as no surprise to anyone in Yorktide when glamorous Carol Ascher fled the little Maine town for New York City. While Carol found success as an interior designer, her younger sister, Bonnie, stayed behind, embracing marriage and motherhood. She even agreed to take in Carol's teenage daughter during a tumultuous patch. Now both their girls are grown and Bonnie, recently widowed, is anticipating the day she'll retire to Ferndean House, the nineteenth-century family home on the rocky Maine coast. But forty-five years after leaving Yorktide, Carol suddenly announces that she's moving back-- into Ferndean. Bonnie is indignant. She's the one who kept the homestead in order and tended to their dying mother. Now Carol expects to simply buy her out? As far as Bonnie is concerned, Ferndean is part of their heritage-- not just another of Carol's improvement projects, to be torn apart and remade according to her whim. The entire Ascher family is in flux, uncovering secrets that upend their relationships. Carol's longing to be welcomed home is fueled by a painful truth she's carried for years. It will take an extraordinary summer-- in a remarkable place-- to lead these women back to each other, buoyed by the tides of friendship and forgiveness.
