At the start of another pitiless winter, the wolves have come for the children of Keelut. Three children have been taken from this isolated Alaskan village, including the six-year-old boy of Medora and Vernon Slone. Stumbled by grief and seeking consolation, Medora contacts nature writer and wolf expert Russell Core. Sixty years old, ailing in both body and spirit, and estranged from his daughter and wife, Core arrives in Keelut to investigate the killings. Immersing himself in this settlement at the end of the world, he discovers the horrifying darkness at the heart of Medora Slone and learns of unholy truth harboured by this village.
