Gregory Maguire creates a fantasy world so rich and vivid that we will never look at Oz the same way again. "Wicked" is about a land where animals talk and strive to be treated like first-class citizens, Munchkinlanders seek the comfort of middle-class stability and the Tin Man becomes a victim of domestic violence. And then there is the little green-skinned girl named Elphaba, who will grow up to be the infamous Wicked Witch of the West, a smart, prickly and misunderstood creature who challenges all our preconceived notions about the nature of good and evil.
