Lindy has the summer of a lifetime planned at her family's beloved cottage in Summerland Cove, Maine, where she's spent summers all her life and where she and her husband David met as teenagers. She's slated big events three weekends in a row: David's fiftieth birthday party, her parents' fiftieth anniversary party, and her oldest daughter Hailey's wedding. But when David doesn't show up for his own party, everything about the life they've created together is thrown into question, as the shattered family sets out looking for him. Has he been in an accident? God forbid, been the victim of a crime? Or is it something more cliche--a midlife crisis, an affair? Surely, he'll show up for his beloved daughter's wedding--won't he? The agonizing days tick by and still no David. Lindy's four nearly grown children are panicked. Lindy struggles to remain calm, even as long-buried details of the family's past begin to surface, offering distressing clues. Meanwhile, her mother seems to be harboring secrets of her own, her father has grown alarmingly absent-minded, and Hailey wrestles with whether she should get married at all--even if her father does turn up.
