Fourteen people are trapped on Skek, a barren island in the middle of the North Sea somewhere between the coasts of the UK and Denmark. Life there is fragile and tough. One slip is all it takes. A momentary lapse leads to a tragic accident, but when the body count quickly starts to rise, questions are inevitably asked. Are the deaths coincidental, or something else entirely? Those people you thought you knew, can you really trust them? Is the person standing next to you a killer? Will you be their next victim?

A horrific discovery changes everything, and a trickle of rumours becomes a tsunami of fear. Is this the beginning of the end of everything, or a situation constructed by the mass hysteria of a handful of desperate and terrified people?

“Moody really knows how to write creeping, claustrophobic terror, effectively sneaking up on his readers and, finally, scaring the life out of them. Top-drawer horror.” —Booklist (starred review)
