Wow. I thought the book was excellent. I honestly loved the whole series... In fact, the musical was really watered down and somewhat awful in comparison. They changed so much in the musical that it is tough to even give both of these works the same name...what they did was take away all of the important storylines dealing with the prejudice of society and added in a really terrible love triangle that really didn't exist in the first place. And on top of it all, they changed all the characters around so much as if to try and tie in with the original Wizard of Oz more...but in doing that, all it did was create humongous plotholes that will never be explained. And the worst part is that in the musical, she CHOOSES to be Wicked...she states it many times within song. Whereas in the book, she NEVER made that kind of a decision...it is only up to the READER to make that decision.
Why do I love the book so much? I love how it skews good and evil so much that you are actually forced to come up with your own opinion as to which characters are good and which characters are plain awful, rather than the author just telling you as they do in most stories. The book is about how there is no perfect world. Once you think you stumble upon it, you finally realize that the rainbows and puppies will always come with the price of vengeance and dark thoughts. I love this book, because it touches on race, class, gender, animal rights and religion all without trying to GIVE you an answer. It's so filled with strength and hope..but also filled with despair and non-triumphs. But mostly because the story is so intriguing. Following Elphaba through her childhood, college years, adulthood, etc. she is faced with so many trials, in a quickly deteriorating Oz. I love the way that no matter how much good she does, it is brilliantly spun as evil by outside forces. You can take a lot from this book. The only thing you can take from the musical is "hey look at the pretty costumes and the catchy songs..." Ah well, too each their own
