A powerful, provocative novel about marriage and motherhood, love and forgiveness. Tessa Russo is a stay-at-home mother of two young children and the wife of a renowned pediatric surgeon. Valerie Anderson is an attorney and single mother to six-year-old Charlie—a boy who has never known his father. Although both women live in the same Boston suburb, they are strangers to one another and have little in common, aside from a fierce love for their children. But one night, a tragic accident causes their lives to converge in ways no one could have imagined. This is the moving, luminous story of good people caught in untenable circumstances. Each being tested in ways they never thought possible. Each questioning everything they once believed. And each ultimately discovering what truly matters most.
