Wicked: The Life and Times of the Wicked Witch of the West - Gregory Maguire

A fairy tale for grownups, this book gives you the Witch's Eye view of the story of Oz. Starting before her birth, it explains how the Wicked Witch came to be, her family, her friends and her part in the underground rebellion against the Wizard of Oz. While travelling off the beaten Yellow Brick Road, she examines Animal Rights, the nature of good and evil, god, the afterlife, love and forgiveness.

I highly recommend it, and I plan on reading more Gregory Maguire as soon as possible.
