Two brothers fight to save a group of soldiers on a rocky island in the Hebrides in this haunting adventure by an "exceptional" thriller master (TheGuardian).

The island of Laerg towers over the North Atlantic, a forbidding black rock with cliffs impossible to climb, its farthest heights wreathed in fog. It's an inhospitable place, whose last residents were forcibly evacuated in the 1930s, but Donald Ross, the artist son of an islander, has spent his life imagining its rugged beauty. When he finally comes home, however, the isle of his dreams may become his tomb.

Donald is searching for his brother, Iain, believed lost at sea many years ago. He finds him living under an assumed identity at the British army outpost that now dominates Laerg. The weather soon turns sour, and the moment to evacuate draws near, but Iain delays. He's seeking something on the rocky cliffs, and to find it he will sacrifice his sanity, his men, and his soul.

Based on the Hebridean island of Hirta, Laerg is a truly unique creation—a place so real, so tantalizing, so utterly dangerous that readers will feel they have traveled there, to feel the salt wind at their backs and the bloody sand beneath their feet.
