The Search Party by Hannah Richell

A spellbinding locked-room mystery about a glamping trip gone horribly wrong when a powerful storm leaves the participants stranded and forced to confront long-held secrets and a shocking disappearance.
Max and Annie Kingsley have left the London rat race with their twelve-year-old son to set up a glamping site in the wilds of Cornwall. Eager for a dry run ahead of their opening, they invite three old university friends and their families for a long-needed reunion. But the festivities soon go awry as tensions arise between the children (and subsequently their parents), explosive secrets come to light, and a sudden storm moves in, cutting them off from help as one in the group disappears.

Moving between the police investigation, a hospital room, and the catastrophic weekend, The Search Party is a propulsive and twisty destination thriller about the tenuous bonds of friendship and the lengths parents will go to protect their children—perfect for fans of Ruth Ware and Lucy Foley.
