Ernt Allbright, a former POW, comes home from the Vietnam War a changed and volatile man. When he loses yet another job, he makes an impulsive decision: He will move his family north, to Alaska, where they will live off the grid in America's last true frontier. Thirteen-year-old Leni, caught in the riptide of her parents' passionate, stormy relationship, dares to hope that a new land will lead to a better future for her family. Her mother, Cora, will do anything and go anywhere for the man she loves, even if it means following him into the unknown. At first, Alaska seems to be the answer to their prayers. In a wild, remote corner of the state, they find a fiercely independent community, and the generosity of the locals makes up for the Allbrights' lack of preparation and dwindling resources. But as winter approaches, Ernt's fragile mental state deteriorates and the family begins to fracture. In their small cabin, covered in snow, blanketed in eighteen hours of night, Leni and her mother learn the terrible truth: They are on their own. In the wild, there is no one to save them but themselves.
