It is the first of The Wicked Years series, followed by Son of a Witch (published in 2005), A Lion Among Men (published in 2008), and Out of Oz (published in 2011).
In 2003, it became the basis for the broadway musical, Wicked: The Untold Story of the Witches of Oz.
The novel is a political, social, and ethical commentary on the nature of good and evil, and takes place in The Land of Oz, in the years leading to Dorothy's arrival.
The story centers on Elphaba Thropp, the misunderstood green-skinned girl who grows up to become the notorious Wicked Witch of the West.
