Yellow Brick War

Amy Gumm grew up in Kansas, and like Dorothy before her, a tornado carried her off to Oz. There she learned that the land's values are reversed: Good is Wicked, and Wicked is Good. The Wicked Witches trained her for one job, assassin.

Her target is Dorothy, who threatens to destroy both Oz and Kansas. Amy was supposed to be the only one able to kill her, and she failed. Other people died for her mistakes.

The cost of that failure is a portal now standing open between the two worlds. If Amy cannot close it, Dorothy will make sure she never sees home again.

This is the third book in the Dorothy Must Die series, told in Amy's own first-person voice. Her to-do list is blunt: join the Witches, fight for Oz, save Kansas, and finally stop Dorothy. Reading it means following a girl who has already lost a round and has to win the next one.
