After saving the world from the diabolical Ace of Anarchy, Ella, Brigit, and Jason return for year three at the Arcanum Training Institute. But the heroes return is far from welcoming. Ella’s big reveal last year threw everything into chaos, unearthing long-buried secrets and unwinding a twisted trail of deceit. As tensions rise between Marvellers and Conjurors, Ella realizes that the only way to end the chaos is to unveil the truth about what happened to the Conjure architect once and for all. To do that, she’ll have to enlist the help of the living and the dead. As they plunge deeper into the truth, the search leads them to the Underworld and the Cards of Deadly Fate—an impenetrable prison for supervillains. But before Ella can figure out how it’s all connected, the tension between magical worlds boil over, threatening everyone around her. Will Ella and her friends uncover the truth about the missing architect before their worlds collide?
