When Nora and her little sister unravel another magical map given to them by Miss Getaway, they find themselves at the River's Heart on a journey filled with exploration, fun, and imagination. After Nora realizes she's lost the map, their ticket home, she worries that the journey might be too much for her sister, who is tired and overstimulated after a long day. Fortunately Nora knows just the thing to keep her sister moving: the art of distraction! The sisters lean on their imaginations to guide them to the map and back home. The third book in a series by children's author Kevin DuBois, She's My Sister: River's Heart celebrates the loving bond between two sisters and the wild and wonderous adventures on which they embark.
