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.
In this sequel to Trouble in the Trees, it's the end of grade six and Bree plans to spend the summer hanging around her townhouse complex in Vancouver, climbing trees with her friends. But her parents have other plans for her; she is going to Ontario to stay with her grandma who lives on a farm "in the middle of nowhere." A farm that is about to be destroyed by a superhighway unless Bree can stop it. Convinced that saving the land will end her grandma's unhappiness, Bree tries to rally cousins and neighbors, but instead of finding help, Bree uncovers some shocking things about her relatives. The more Bree gets to know about her extended family and their farm, the more complicated everything becomes. If she isn't able to save the farm, can she at least manage to save her family?
