Eleven-year-old Bree is happiest when she's climbing the trees at Cedar Grove, her urban townhouse complex. She's the best climber around, even better than an older boy, Tyler, who drives her crazy with his competitiveness. When Ethan, a younger boy, falls from a tree and hurts his elbow, the neighborhood council bans all tree-climbing in Cedar Grove. If Bree chooses to ignore the bylaw, her family could be kicked out of their home, so she vows to change the rule instead. After giving a presentation to the Neighborhood Council, she realizes this is not a battle she can win on her own, but rallying the Cedar Grove troops is more difficult than she imagined.
