The book's action is split between Woodstock, New York and New York City, depending upon which parent Phoebe is with. Woodstock means peace and safety while the big city Phoebe once thought of as home quickly becomes foreign and somehow threatening. She travels between the two on the Divorce Express, a bus which carries many children in the same situation every weekend. Living in two places can be very disorienting, and Phoebe has a hard time thinking of either place as her true home.
