The wicked will rise

Amy Gumm is the "other" girl from Kansas, who after a tornado sweeps through her trailer park is sent to Oz as well. However, she finds it a very different place than did the most-famous Kansas girl in Oz, and it is all that girl's fault--Dorothy has returned to Oz to steal its magic, Glinda is no longer a Good Witch, and the remaining Wicked Witches have formed the Revolutionary Order of the Wicked in order to take Dorothy down. The Order recruits Amy to their cause.
