I saw it in April in Chicago, and I'm seeing it again in Chicago in late October.
According to Wikipedia-
"Wicked is a political, social, and ethical commentary on what good and evil really are. The story centers around
Elphaba, the misunderstood green-skinned girl who grows up to become the infamous
Wicked Witch of the West. Elphaba acquired her green skin through one of her mother's affairs (a man of unknown ethnicity and a green liquid in a green bottle that he feeds to the pregnant Melena) and was also born with incredibly sharp teeth. It tells of her time at
Shiz University, as well as her journey to the
Emerald City and
The Vinkus, among other places in Oz. The book explains Elphaba's motives and examines her true personality. Many familiar characters from Oz are featured in
Wicked, including
the Wizard,
Glinda (here originally called "Galinda" but later adopting the name Glinda out of respect for Dr. Dillamond who often mispronounced her name),
the Wicked Witch of the East (here called
Nessarose), and
Dorothy. Maguire also introduces several new characters including
Fiyero,
Madame Morrible, and
Doctor Dillamond."
