Dorothy and friends free Glinda and Adraste, but something– make that a lot of somethings– would see them all dead. Is it too late for the world of Oz anyway? Back in the Emerald City, the Heart of Oz is finally unearthed– and nobody was expecting what they found. And the truth about the Wizard is revealed, as his power grows even more dangerous!
Oz has been ruled by the Wicked Witches, sieged by The Warlord, and even corrupted by the dark magic of Zamora, yet it still stands. Now the dawn of a new age of Oz has arrived. There is calm in the lands, happiness in its homes, but a shadow is creeping into the hearts and minds of its citizens and with it comes a new evil. Oz must prepare for a battle that will determine the fate of the very soul of the Emerald Kingdom, when The Wizard makes his move!
