Donna Weaver has put everything she has into restoring The Breakers, an old bed and breakfast on a remote stretch of beach in Galloway. Now it sits waiting—freshly painted, richly furnished, filled with flowers—for the first guests to arrive.



But Donna's guests, a contentious group of estranged cousins, soon realize that they've been here before, years ago. Decades have passed, but that night still haunts them: a sixteenth birthday party that started with peach schnapps and ended with a girl walking into the sea.



Each of them had made a vow of silence: 'lock it in a box, stitch my lips, and go to my grave.'



But now someone has broken the pact. Amid the home-baked scones and lavish rooms, someone is playing games, locking boxes, stitching lips. And before the weekend is over, at least one of them will go to their grave.
