To make Oz a free land again, Amy Gumm was given a mission: remove the Tin Woodman’s heart, steal the Scarecrow’s brain, take the Lion’s courage, and then Dorothy must die... But Dorothy still lives.

Now the Revolutionary Order of the Wicked has vanished, and mysterious Princess Ozma might be Amy’s only ally. As Amy learns the truth about her mission, she realizes that she’s only just scratched the surface of Oz’s past—and that Kansas, the home she couldn't wait to leave behind, may also be in danger.

In a place where the line between good and evil shifts with just a strong gust of wind, who can Amy trust—and who is really Wicked?

My name is Amy Gumm—and I’m the other girl from Kansas. After a tornado swept through my trailer park, I ended up in Oz. But it wasn’t like the Oz I knew from books and movies. Dorothy had returned, but she was now a ruthless dictator. Glinda could no longer be called the Good Witch. And the Wicked Witches who were left? They’d joined forces as the Revolutionary Order of the Wicked, and they wanted to recruit me. My mission? Kill Dorothy.

Except my job as assassin didn’t work out as planned. Dorothy is still alive. The Order has vanished. And the home I couldn’t wait to leave behind might be in danger. Somehow, across a twisted and divided land, I have to find the Order, protect the true ruler of Oz, take Dorothy and her henchmen down—and try to figure out what I’m really doing here.
