Molly's life is gleaming and beautiful on the surface. Married to Tanner, a cosmetic dentist, she has a daughter finishing high school and twin stepsons from Tanner's first marriage. No one in her exclusive Massachusetts neighborhood knows what living with the demanding Tanner is really like. They know even less about the life she left behind in Florida almost two decades ago when she was Maddy Carmichael, living with her twin brother and neglectful mother in a run-down train park. After the terrible events of her high school prom night, she fled north and reinvented herself. But the veneer of Molly's existence is cracking.
