In this propulsive locked-room thriller, a reunion weekend in the French Alps turns deadly when five friends discover someone has deliberately stranded them in a deserted mountaintop resort

When former snowboarder Milla is invited to a reunion at the French Alps resort that saw the peak of her career, she drops everything to go. The group haven't seen each other since the disappearance of the beautiful and enigmatic Saskia ten years ago, and while Milla has tried to bury the events of that winter, the invitation comes from Curtis - how could she say no?

But when an icebreaker game turns menacing, the five friends realise they don't know who has actually gathered them there and how far they will go to discover what really happened to Saskia. In an isolated lodge high up a mountain, the secrets of the past are about to come to light.

Imagine Agatha Christie set in the Alps and you have Shiver, a spectacularly sinister psychological debut.
