Martha is incredibly unpopular. She’s overweight, buck-toothed, and shy. Ivy is an outcast. Her family lives on the outskirts of town amid a field of derelict orchards. But starting in second grade, the girls form a bond that allows them to take control of their own lives.
It all begins when Ivy tells Martha that she is no ordinary girl: She claims she’s a changeling, switched with the real Ivy at birth. With the strength of Ivy’s friendship, Martha becomes more confident and sure of herself. And through their bond, Ivy gains the normalcy she needs, away from life with her tumultuous family. When the two girls play, they enter an elaborate fantasy world all their own. But when the real world threatens to split them apart, their friendship becomes more important than ever.
