"Someone's taking it," I said....
"It's Dorothy," I realized. "Dorothy's stealing the magic."
"Now you've got it," Glamora said. "And losing its magic to Dorothy will mean the end of Oz. That's why you're here. We need you to stop her...."
"Me? I just got here. How am I supposed to stop anyone from doing anything?"
...."Simple. You're going to kill her." She looked right at me and said, "Dorothy must die."
Salvation Amy, that's what the kids call her. Amy Gumm lives in Kansas in a trailer park with her dead-beat mother. One evening a tornado sweeps through her town, depositing Amy and her pet rat, Star, in Oz. Amy soon learns that Dorothy found a way to return to Oz and take control of the land and its magic. Dorothy turned evil, is destroying Oz and enslaving its people.
Amy is recruited by the Revolutionary Order of the Wicked where she is trained to fight. Her mission is simple, remove the Tin Woodman's heart, steal the Scarecrow's brain, take the Lion's courage and then - Dorothy Must Die.
