Kids vs. parents! An epic treehouse sleepover! An awesome group of friends! An exciting new book from National Book Award finalist Lisa Graff. Winnie's last day of fourth grade ended with a pretty life-changing surprise. That was the day Winnie’s parents got divorced, the day they decided that Winnie would live three days a week with each of them and spend Wednesdays by herself in a treehouse smack between their houses, to divide her time perfectly evenly between them. It was the day Winnie’s seed of frustration with her parents was planted, a seed that grew and grew until it felt like it was 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 her. It’s kids versus grown-ups, and no one wants to back down first. But with ten kids in one treehouse, all with their own demands, Winnie discovers that things can get pretty complicated pretty fast! Even if they are having the most epic slumber party ever. In the newest novel by beloved National Book Award finalist Lisa Graff, kids have turned the tables on their parents, and all the rules have been tossed out the window. But does Winnie have what it takes to hold her ground and keep everyone happy?
