He writes her letters. She writes him off.

Prince Louis has two problems: a royal reputation in ruins and a stubborn crush on the one woman least likely to fall for him—his frenemy's fiercely independent younger sister. Princess Bethany fled the crown years ago for a bohemian life in Paris, trading palace walls for piano keys and protocol for personal freedom. She's queer, polyamorous, and entirely uninterested in love, let alone with a man like Louis.

But when fate throws them together, Louis launches an unexpected campaign to win her over—one scorching love letter at a time. As Bethany starts to see the man behind the title, she's torn between the pull of her heart and the fear of losing herself to the very institutions she swore to avoid: monogamy, marriage, and monarchy.

When everything shifts and Louis must step into a role he never wanted, Beth faces an impossible decision—stay true to herself or take a chance on a future she never imagined.

Fall in love all over again in this sensual, slow-burn continuation of the Regency and Rivalry series—where royalty meets rebellion, and even the coldest hearts can be rewritten.
