For a family with four kids, two dogs, assorted cats, and a constant stream of family and friends dropping by, life in the Austin family home has always been remarkably steady and contented. When a family friend suddenly dies in a plane crash, the Austins open their home to an orphaned girl, Maggy Hamilton. The Austin children — Vicky, John, Suzy, and Rob — do their best to be generous and welcoming to Maggy.
Vicky knows she should feel sorry for Maggy, but having sympathy for Maggy is no easy thing. Maggy is moody and spoiled; she breaks toys, wakes people in the middle of the night screaming, discourages homework, and generally causes chaos in the Austin household. How can one small child disrupt a family of six? Will life ever return to normal?
