Rebecca Randall is one of seven fatherless children, but is full of fun and strange ideas. She leaves her family at Sunnybrook Farm and goes to live with her two aunts in Riverboro. There she goes to school for the first time, embarks on a madcap scheme to sell soap, nearly runs away, befriends the kindly stagecoach driver Jeremiah Cobb, and with 'Mr Aladdin' helps repair her family's fortunes.
