Return to L. Frank Baum’s wonderful world of Oz with this illustrated children’s book series. Three emerald necklaces cause everyone in Oz to forget all about Princess Ozma, the Wizard, and Glinda the Good and acknowledge instead a fat old king named Skamperoo as supreme ruler! The mystic enchantment is responsible as well for the appearance of the glorious Wishing Horse, the most magnificent white steed imaginable.   Only Dorothy and Pigasus, the flying poetical pig, can save the realm. . . .   Praise for the Oz series   “Where the young stay young and the old grow young forever—these books are for readers of all ages.” —Ray Bradbury   “The land of Oz has managed to fascinate each new generation. . . . The Oz books continue to exert their spell . . . and those who read [them] are often made what they were not—imaginative, tolerant, alert to wonders.” —Gore Vidal   “I was raised with the Oz books, and their enchantment, humor and excitement remain with me. They are still a joy and a treasure. I welcome this Oz revival.” —Stephen R. Donaldson
