We all know the story of Jack and the Beanstalk, but very few people know Jack had a sister named Jill. This is her story. When Jill receives some magic beans of her own, she reaps, not an enormous bean stalk, but an enormous field of bean plants. Suddenly, the family no longer has to worry about having enough to eat. Indeed, they now have more than enough food to share with their friends and neighbors. But before they can do so, Jill must find a way to deal with two older girls who see in her good fortune only an easy way to make a fortune of their own. Thanks to some help from a clever mouse, and her own courage and determination, Jill succeeds in meeting a challenge as daunting as that of her brother, Jack.
