Wastelands of Oz by Kasey Hill
The Return to Oz series Book 1
Somewhere...down a wrong road...under the sea...across the desert...by earthquake, tornado, hurricane, and magic... exists the Land of Oz. But it's not the same land you loved and dreamed of. A new and more powerful evil than that of the wicked witches has taken over Oz by the name of the Red Sorceress. Oz is in shambles, a barren wasteland. Dorothy is sick with stomach cancer, so it is up to her daughter, Maryjane, to help bring Oz back to life. Maryjane isn’t your average teenager in Kansas. She was blessed by the Elders of Oz with magical powers as a thanks for the help her mother offered while living there. Glinda’s son, Charlie, and Maryjane are the heirs to the throne of Oz, while the Red Sorceress intends to steal it away for her and her apprentice. Maryjane and Charlie have battled for years over their feelings for each other and have grappled with the idea of punishment, for Maryjane is a mortal from the human world, and it is forbidden. However, the only way to defeat this new monster of evil is together, and they alone share the hidden powers to bring Oz back to life and return the wastelands back into the voluptuous land it once was.
