Its 1981, and thirteen-year-old Roscoe McAdams and his brother and sister have always lived with their parents, Sebastian and Moonstar, in an isolated cabin high on a ridge in Californias northern Sierra, though often in spring when Moonstar cant stand the snow anymore she takes them for a stay down below. Theyve mostly been home-schooled. Then, through a fluke that April, Moonstar becomes a substitute teacher in a small town and enrolls the kids in school there. Roscoe assumes that when summer comes, theyll go back to the ridge and Sebastian: thats how its always been. But they dont, and then everything Roscoe thinks he knows for sure begins to fall apart.
