The Enchanted Lies of Céleste Artois

In this lush and lyrical fantasy, Ryan Graudin transports readers to the hidden magical pockets of early 1900s Paris, a place of enchanted salons, fortune tellers who can change your stars, and doorways that can take you to the most unexpected places—and introduces readers to the delightful Céleste Artois, a con artist who will make a deal with the devil in exchange for her life...and change the fate of the world. 

Once, Céleste Artois had dreams of being an artist. But when the creative elite of Paris dashed those plans, she turned her talents to forgery and cons. She and the Enchantresses—her two fellow thieves and best friends—see Paris as a rich hunting ground for marks. Yet even though their hideout in Peré Lachaise cemetery is bursting with francs, Céleste cannot rest. There is always more to take. And the blood she has begun to cough into her handkerchief means her time is running out.
 
But everything changes when she encounters Rafe, a mysterious and beautiful stranger who leads her to an enchanted salon—a place where artists can bring wondrous imaginations to life. Céleste is captivated by this establishment, and learns of the existence of magical Paris, hidden in the pockets and alleys of the ordinary world, if one only knows where to look. 

Rafe offers Céleste an irresistible deal: the gift of time in exchange for lending him and his benefactor her forging talents. But one must be careful making deals with devils, and there's more to this hidden world than meets the eye. Shadows have begun to circle Paris. And soon, the Enchantresses will find that true magic is far more powerful, and deadly, than they ever imagined.
