After seeing the musical twice, I decided to read the book, Wicked, and it was a very interesting read. The author explores the fine line that can separate the differences and struggles between good and evil; and the underlying results in social society, politics, religion, business, education, and friendships as pertaining to life and death. "It can get a little "preachy" at times, but it causes one to think about ones own relavence to life and society as a whole.
I did find the script for the musical took a lot of dramatic license with the story, but I think most of them do, to make it a better fit to the stage.
The author also other books showing the other side of the story of popular books made into movies such as Mirror, Mirror and The Confessions of an Ugly Stepsister.
