From Ruth Ware, the #1 New York Times bestselling author of In a Dark, Dark Wood, The Woman in Cabin 10, The Lying Game, The Death of Mrs. Westaway, and The Turn of the Key, comes her highly anticipated sixth novel. Getting snowed in at a mountain chalet doesn't sound like the worst problem in the world. Especially when there's a breathtaking vista, a cozy fire, and company to keep you warm. Unless that company happens to be eight coworkers... none of whom you can trust. When an off-site company retreat meant to promote mindfulness and collaboration goes utterly wrong with the arrival of a monster storm, the corporate food chain becomes irrelevant and survival trumps synergy. Come Monday morning, how many members short will the team be?
