On the wind-battered island of Altnaharra, off the wildest coast of Scotland, an isolated clan awaits the end of the world—and the beginning of another. They worship the Adder, a mysterious power they believe will soon return and choose one of them as its heir.

Every member longs to be chosen, but young Eve is prepared to sacrifice anything for the honour. When Chief Inspector Black arrives to investigate a brutal murder and a sacred ceremony ends in bloodshed, the clan’s carefully guarded beliefs begin to unravel—and the dark secrets of Altnaharra are finally exposed.

An atmospheric gothic horror about faith, family, manipulation and the devastating consequences of surrendering yourself to something that promises salvation.
