Alaska State Trooper Logan Gibson has buried his past deeper than the winter snows of America's Last Frontier. But when someone close to him vanishes, leaving behind a cryptic message meant for his eyes alone, Gibson is forced to excavate secrets he swore would stay hidden.

A methodical killer stalks the vast Alaskan wilderness, taunting authorities with haunting photographs that only Gibson can decipher—Gibson and the friend who's now missing. As bodies begin to surface and time runs thin, Gibson must turn to his friends in the Arctic Circle Murder Club for help.

From treacherous mountain peaks to the merciless depths of frigid waters, Gibson will do anything to stop this killer. Because in Alaska, the cold isn't the only thing that kills.
