Dorothy and the Seven-Leaf Clover is an Oz book for younger readers, written by Dorothy Haas and illustrated by David Rose. Toto falls victim to an old spell, left over from the days of the Wicked Witch of the West. Chasing a mouse into a twisting cornfield, the dog is caught in a golden summer house by a solid-gold boy with a cold heart. To free her dog from its malevolent magic, Dorothy Gale and her companions the Scarecrow, Tin Woodman, and Cowardly Lion need to find a seven-leaf clover, one of the rarest plants in Oz. Once the gold boy can wish on the clover, he can set himself and Toto free once more.
