A new power has risen in the land of Oz, known only as the "Dark Wizard." The Dark Wizard intends to steal Glinda's Great Book of Records, which keeps track of everything that has ever happened in Oz, as well as each event as it currently happens. He plans to use it to set all the most evil plots of destruction into motion at once.
Never fear, citizens of Oz! Joshua, Tamara, Tommy and Laura are also searching for the Great Book of Records, to erase the fact that they had ever been in Oz. The only problem is: Joshua is stuck in Mifkets Asylum, so when his prophecy comes calling in Oz, who will pay the price?
