We are taking you to the Land of Oz! You may have seen the movie "Wicked," but before it was a movie, it was a hit Broadway musical. And before that, it was a book originally published in 1995. While the book and the movie are much different, the author of the book "Wicked," Gregory Maguire, is out with a new book called "Elphie." It's a prequel that dives into Ephaba's childhood. What happened to the Wicked Witch of the West before she gets to Shiz University? Whitney got to talk to Maguire about the new book, why he chose to write it now, and what it was like to visit the film set!
