In 1843 New Orleans, the reigning Voodoo queen is Marie Laveau, feared by her enemies and followers alike. Her daughter, Marie "Ree" Laveau the Second, is everything her cutthroat and principled mother is not--spoiled and entitled, with a wickedly rebellious streak--and defies her mother at every turn. But Ree's world is turned upside down when she finds Marie comatose in the bayou, cursed by exiled Voodoo king Jon the Conjurer--Marie's former teacher, lover, and greatest enemy. As Marie hovers on the brink of death, Ree races to uncover the secrets of her mother's life in search of a cure and gradually uncovers a web of alliances, dangers, and deception. What's worse, Henryk Broussard, Ree's long-missing childhood best friend, returns as a witch hunter of the Church, tasked with investigating her. With so many enemies circling, including a puritanical-minded Brotherhood of alchemists and the slave-holding mayor of the city, Ree must confront the past and face her mother's demons that have now become her own--or die trying.
