Possession. Power. Passion. New York Times bestselling novelist M. J. Rose creates her most provocative and magical spellbinder yet in this gothic novel set against the lavish spectacle of 1890s Belle Époque Paris.

Sandrine Salome flees New York for her grandmother’s Paris mansion to escape her dangerous husband, but what she finds there is even more menacing. The house, famous for its lavish art collection and elegant salons, is mysteriously closed up. Although her grandmother insists it’s dangerous for Sandrine to visit, she defies her and meets Julien Duplessi, a mesmerizing young architect. Together they explore the hidden night world of Paris, the forbidden occult underground and Sandrine’s deepest desires.

Among the bohemians and the demi-monde, Sandrine discovers her erotic nature as a lover and painter. Then darker influences threaten—her cold and cruel husband is tracking her down and something sinister is taking hold, changing Sandrine, altering her. She’s become possessed by La Lune: A witch, a legend, and a sixteenth-century courtesan, who opens up her life to a darkness that may become a gift or a curse.

This is Sandrine’s “wild night of the soul,” her odyssey in the magnificent city of Paris, of art, love, and witchery.
