It's a beautiful day in Newport, Rhode Island, when Phoebe Stone arrives at a grand beachside hotel wearing her best dress and least comfortable shoes. Immediately she is mistaken for one of the wedding people - but she's actually the only guest at the Cornwall Inn who isn't here for the big event. Phoebe has dreamed of coming here for years. She hoped to shuck oysters and take sunset sails with her husband but now she is divorced and depressed, and not sure how to go on. She's not been sure how to do anything, lately, except climb into bed and drink gin and tonics and listen to the sound of the refrigerator making ice. When the bride discovers her elaborate destination wedding could be ruined by this sad stranger, she is furious. She has spent months accounting for every detail and every possible disaster - except for, well, Phoebe . . . Soon, both women find their best-laid plans derailed and an unlikely confidante in one another.
