One lives high in the sky. The other lives deep underground. Hang Glider and Mud Mask is the magnificent story of two unlikely friends who fly down and climb up to meet each other half wayon the surface of the earth, and in the center of the book! Starting on one side of the book, follow Mud Mask as she leaps, climbs, and escalators her way toward the sunlight. Or, turn the book over and around, and follow Hang Glider as he glides and twists toward the ground.
