Welcome to Emerald Academy: School of Oz. Emily Gale, the daughter of Dorothy, is beyond excited to begin at Emerald Academy the school for the future leaders of Oz. She is reunited with her friends, the Scarecrow's son, the Tin Woodsman's daughter, Glinda's son and the Lion's son. But then a new boy arrives. Seth has green skin in a distinct pattern that every Ozian knows. Could he be related to the most evil villain Oz had ever known, the Wicked Witch of the South? When a dangerous magic ball is stolen, suspicions rise and fingers begin pointing at Seth. But Emily isn't sure Seth is as wicked a everyone thinks. And the only hope they have of saving Oz is to trust Seth to go with them along the yellow brick road. For whatever awaits them.
