Its been years since Dorothy was last in Oz. She is older now, but the memories of her time in that magical place have never left her. And the magical slippers that brought her home after her last visit were always with her, serving as a constant reminder. But now, Oz is in peril once again, and the Wizard has brought her back to help. All of her old friends are there: The Scarecrow, the Tin Woodsman, and the Lion…but who is Scraps, and what part does she play in the troubles that are plaguing Oz? Why are the dead coming back to life, and how can an old prophecy save them all? And, in a land where the dead are truly undead, can an old enemy stay down for good?
