At the new house, there were movers and shouting and boxes and blankets. There were many places a girl like Mabel and a boy like Sam could be tripped over or smooshed or trod upon. There was one safe place where they would not. And that is how Mabel became a Sea Captain. In this three-part picture book of moving house and imaginative play, Mabel and Sam sail the high seas of their new home; tour the intriguing museum of their living room; journey through outer space to the safety of their own beds; and discover how far afield—and how close to home—imagination can take them.
