It's a beautiful day in Newport, Rhode Island, when Phoebe Stone arrives at the grand Cornwall Inn wearing a green dress and gold heels, not a bag in sight, alone. She's immediately mistaken by everyone in the lobby for one of the wedding people, but she's actually the only guest at the Cornwall who isn't here for the big event. Phoebe is here because she's dreamt of coming for years-she hoped to shuck oysters and take sunset sails with her husband, only now she's here without him. Meanwhile, the bride has accounted for every detail and every possible disaster the weekend might yield except for, well, Phoebe-which makes it that much more surprising when the women can't stop confiding in each other.
