Unbroken

One morning while at school Harriet Gibson receives some very bad news. Her mother and the horse she was driving have been killed in a mishap with an automobile. Now Harriet's mother and Belle, the mare, are dead, and Harriet and Belle's unbroken colt are orphans. Harriet is devastated to learn that the home she and her mother made together is to be sold, and that she must go to live with her Aunt Sarah, her long-deceased father's sister. Harriet knows that Sarah didn't like her mother and doesn't want her. Harriet moves to her unsympathetic aunt's farm, bringing with her the two things she values most: her mother's sewing machine, and the unbroken colt. But how will she convince Aunt Sarah that she needs to continue going to school?
