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?
