One Square Inch

Cooper's grandfather gives him and his little sister, Carly, deeds to square inches of land in the Yukon. Carly uses them to invent her own imaginary kingdom of Inchland—far away from the silence of their home, where their single mother stays in bed all day. When their mom comes out of her season of sadness bursting with sometimes frightening energy, Carly retreats into Inchland, while sixth-grader Cooper tries to control the chaos. But can Cooper really keep Carly—and himself—safe?
In One Square Inch, Claudia Mills weaves a story that is "Believable and deeply moving" (Publishers Weekly).
