When Winnie's parents get divorced, her frustration at their constant fighting starts to grow until it's as big as a tree itself. By the end of fifth grade, Winnie decides that the only way to change things is to barricade herself in her treehouse until her parents come to their senses—and her friends decide to join. It’s kids vs. grown-ups, and no one wants to back down first. But with ten kids in one treehouse, all with their own demands, things get pretty complicated!
