At 39, Charlotte Casiraghi, daughter of Princess Caroline of Monaco, seems more unstoppable than ever. As 2026 approaches, she’s preparing to release her most ambitious and introspective project yet, her debut solo book, 'La Fêlure,' a title that translates from French as The Crack or The Fracture, which will hit shelves on January 29, 2026, published by the renowned house Julliard.
Far from her roles in fashion and royalty, this new work marks a striking departure and perhaps a declaration of independence. With this new project, Charlotte starts a literary space that has readers excited.
Presented as a “literary and sensitive investigation,” 'La Fêlure' delves into the idea of human fractures, those subtle, often hidden breaks within us, drawing on the lives and words of writers, poets, and adventurers.
It’s not a memoir. Instead, as her publisher puts it, the book should be read “as a journey, a series of variations on a single refrain that if something in us is broken, all the better.”
This isn’t Casiraghi’s first foray into philosophy. In 2018, she co-authored 'Archipelago of Passions' with her former professor, Italian philosopher Robert Maggiori. That book offered a philosophical sketch of emotional states as isolated islands connected by longing, a poetic vision of human feeling.
Having founded the 'Philosophical Encounters of Monaco,' Charlotte is no stranger to the intellectual world. But this new work is distinctly her own and shaped by solitude, study, and deep reflection.
“Philosophy and literature meet in the careful attention to words,” she says. “Not to soften their ambiguity, but to explore it further. That’s what interests me.”
With 'La Fêlure,' Charlotte Casiraghi steps into the literary world not as royalty or fashion icon, but as a writer searching for meaning in the spaces where we break and rebuild. It’s a quiet yet powerful reintroduction, inviting readers to pause, reflect, and consider the beauty that can be found in what is imperfect, unresolved, or undone.
