Paris is a labyrinth of twisted streets, filled with beggars and thieves, revolutionaries and magicians. Seventeen-year-old Camille Durbonne is one of them. She wishes she weren’t.
When smallpox kills her parents, Camille must find a way to take care of her frail, naive sister while minding her volatile, alcoholic brother. Relying on petty magic fueled by sorrow—la magie domestique—Camille painstakingly transforms scraps of metal into money to buy the food and medicine they need. But when the coins won’t hold their shape and her brother disappears with the family’s savings, Camille chooses to pursue a richer, more dangerous mark: the glittering court of Louis XVI and Marie Antoinette.
Using dark magic, Camille transforms herself into the Baroness de la Fontaine. At Versailles, she is swept up into life at court, where aristocrats both fear and hunger for la magie. During a midnight game of hide-and-seek, she comes face-to-face with the mysterious Lazare, Marquis de Sablebois, whom she met, as Camille Durbonne, when his hot-air balloon crashed in Paris’s Champs de Mars. He, too, lives a double life.
As Camille, she soars with Lazare over the rooftops of Paris; as the Baroness de la Fontaine, she gambles at cards, desperate to maintain her status at court and keep herself and her sister off the streets. But la magie has its costs. When a scheming courtier blackmails the Baroness and Lazare’s affections shift, Camille can’t hide her secrets much longer. Then revolution erupts, and she must choose—love or loyalty, democracy or aristocracy, science or la magie—before Paris burns.
