On her return to London, artist and seer Pamela Colman Smith discovers that her nemesis, Aleister Crowley, has returned—and his sights are set on her. Despite Aleister’s efforts to stop Pamela from further developing her tarot deck and accessing its magic, she carries on casting her High Priestess and Empress muses, Golden Dawn society leader Florence Farr and popular theatre star Ellen Terry. But when Ellen is poisoned and nearly killed, Pamela realizes that Aleister won’t stop coming for her—not until her muses are dead. When Aleister reveals his plot to assassinate Queen Victoria and all female rulers, war breaks out between the Aleister’s Carlists and the Golden Dawn. With so many lives on the line—that of the queen, and those of her friends—Pamela must access her inner magic to face the battle of her life.
