Paris, 1823. Victor Beauchne has led a stifling existence, unrecognized for both his cleverness and his gender, except in the pages of his meticulous diary. Abruptly cut off from his family's fortune, he takes the opportunity to start a new life in a shabby boarding house with his beloved spinster aunt Sophie. There, he stumbles upon two kinds of magic: a pen with eerie powers of persuasion and a reserved, alluring art student named Julien.
Brilliant, unconventional Julien is also Julie, a person whose magical paintings can transform their body or enchant viewers. Haunted by a terrible episode in their past, they've come to Paris for artistic success-the ordinary, non-magical kind. Victor, too handsome and far too inquisitive, is a dangerous distraction from their ambitions.
Drawn to each other, Victor and Julie strike up a cautious correspondence of notes slid under doors. It soon unfolds into a passionate romance. Outside the bedroom, their desires clash: Julie wants to distance herself from the world of magic and Victor wants to delve deeper. When the ruthless abuser from Julie's past resurfaces, he aims to take control of her powers and ruin more lives. Victor and Julie are the only ones who can stop him. Do they trust each other enough to survive the threat to their love and their lives?
