In the vein of Lucy Foley's chilling, atmospheric mysteries, a compulsive, psychological thriller about a group of old university friends whose seaside reunion will end in betrayal and murder.

Five old friends . . . One reunion to die for

After years apart, old college friends Aline, Sienna, Rob, Michael, and Brandon reunite in idyllic Dorset, for a weekend at Aline's beautiful house perched on a cliff above the sea. It should be the perfect chance to relax, rekindle friendships, and meet each other's partners; plus, there's a sitter to watch the kids.

What most of the guests don't know, however, is that Aline has called them all together for a reason: someone has threatened to expose the dark crime they committed at university. Long ago, these old friends swore one another to silence, and have never spoken of the deed since. But now, menacing postcards have begun to appear--and Aline is convinced it's one of them turning on the rest.

In Liza North's propulsive and unsettling dual timeline narrative, truths emerge, secrets surface, and long-simmering grudges explode--and by the end of this reunion weekend, at least one of them will be dead . . .
