Five old friends.

One glamping weekend.

A storm that will change everything.

Max and Annie Kingsley have left the London rat race to set up a glamping site in the wilds of Cornwall. They invite old university friends - TV star Dominic, doctor and new mum Kira, and free-spirited Jim and Suze - and their children for a trial weekend but the reunion quickly veers off-course.

First, there's The Incident around the campfire on the first night. The following afternoon, a storm quickly develops off the rugged North Coast. When one of their group goes missing, all hell breaks loose. And as the winds batter the bell-tents, emotions run high and tension mounts for all the characters.

Who is lying in hospital, who has gone missing and who is the body on the beach below the cliffs . . .?

Gripping, cleverly structured and brimming with secrets and lies, this is a masterclass in narrative tension and a chilling exploration of the ways in which aspiration and anxiety collide. It will keep you guessing until the last page.
