Cloudhoppers (Hardcover) (ISBN-13: 9798987918005)

A lazy summer day in the backyard of their grandparents' house turns topsy-turvy for four children and a dog when the skies darken, and the winds pick up. With a flash of lightning and a clap of thunder, they find themselves floating away on the clouds, lost in a world of Cloudhoppers. Follow the children on a magical adventure as they search for a way home. The good people of the clouds help them along... but a band of rowdy kids and a man named Lord Nim have other plans.
