"My name is Amy Gumm. You might remember me as the other girl from Kansas. When a tornado swept me away to the magical land of Oz, I was given a mission: Dorothy must die. That's right, everyone's favourite Wicked-Witch-slayer had let the magic of Oz corrupt her. She turned evil. So I killed her. But just when we thought it was safe to start rebuilding the damaged land of Oz, we were betrayed. Now I m following the Road of Yellow Brick as it helps me escape toward the mysterious land of Ev, where the Nome King rules a bleak and angry world. And what I'm about to find is shocking. My original mission may not have been successful. I thought my job was over, but it's only just beginning. And it's up to me to foil Dorothy's plans for revenge and finally save the land I've come to love." -- Provided by publisher.
