In this third book in the New York Times bestselling Dorothy Must Die series, new girl from Kansas Amy Gumm is caught between her home-and Oz. My name is Amy Gumm. Tornadoes must have a thing about girls from Kansas, because-just like Dorothy-I got swept away on one too.

I landed in Oz, where Good is Wicked, Wicked is Good, and the Wicked Witches clued me in to my true calling: Assassin. The way to stop Dorothy from destroying Oz-and Kansas-is to kill her. And I'm the only one who can do it. But I failed. Others died for my mistakes. Because of me, the portal between the worlds has been opened. And if I don't find a way to close it? Dorothy will make sure I never get to go home again. Now it's up to me to: join the Witches, fight for Oz, save Kansas, and stop Dorothy once and for all.
