When the body of a young woman is found dead beneath the cliffs of the deserted Icelandic village of Kalfshamarvik, Ari Thor Arason uncovers a startling and terrifying connection to an earlier series of deaths, as the killer remains on the loose... Two days before Christmas, a young woman is found dead beneath the cliffs of the deserted village of Kalfshamarvik.

Did she jump, or did something more sinister take place beneath the lighthouse and the abandoned old house on the remote rocky outcrop? With winter closing in and the snow falling relentlessly, Ari Thor Arason discovers that the victim's mother and young sister also lost their lives in this same spot, twenty-five years earlier. As the dark history and its secrets of the village are unveiled, and the death toll begins to rise, the Siglufjordur detectives must race against the clock to find the killer, before another tragedy takes place.
