Nora Walker is all alone in the world. Her whole family are rumored to be witches, which sets her apart from other kids her age. Her grandmother is dead, and her mother is something of an absentee parent. And now that winter has set in at Jackjaw Lake, all the tourists are gone, leaving behind only Nora in her cottage and the residents of the nearby camp for delinquent boys. Nora’s isolation increases still further when a storm drops four feet of snow on the area, cutting off the roads and knocking out the phone lines.
