By now, no one doubts that Carlota Casiraghi is the most intellectual of the children of Caroline of Monaco and the sadly departed Stefano Casiraghi, who died in an offshore accident in the Bay of Monte Carlo on October 3, 1990. Now she has decided to take a very significant professional step: she will publish her first solo book.

It is about La grita, which will be released on January 29 with Julliard Publishing, according to information published by Livres Hebdo. The granddaughter of Rainiero of Monaco and the unforgettable Grace Kelly embark on this occasion on a literary and also emotional investigation that revolves around the concept that gives the title to the book, «the notion of cracks, inspired by the writings and destinies of writers, poets and adventurers».

From what has been learned so far, Carlota Casiraghi has explored in this work the life and work of personalities from different social strata. Thus, its pages traverse the sailor Bernard Moitessier, the writers Ingeborg Bachmann, Colette and Marguerite Duras, the poet Anna Akhmatova and the singer J.J. Cale, which gives us a measure of the breadth of her horizons.

The publisher has issued a statement as a preview of Carlota Casiraghi’s work, who had previously been the partner of the French actor of Moroccan origin Gad Elmaleh: «This book is not a treatise, nor a history, nor, by any means, a confession. It should be understood more as a journey, a series of variations on the same theme, the refrain through which a fixed idea is repeatedly echoed».

Carlota Casiraghi’s Previous Book

Carlota Casiraghi is the president and founder of the Monaco Philosophical Encounters and has long been devoted to study. Her mother, Caroline of Monaco and she, have shared many readings since childhood, and this book is the result of several months of reflection that comes to us full of enthusiasm.

In an interview granted last June to the newspaper La Tribune Dimanche, she offered a preview of her theses and her view of life that we are now going to see rendered in black on white: “Philosophy and literature come together in the attention to words, not attempting to soften this ambivalence but exploring it further. That is what interests me.”

We should recall Carlota Casiraghi’s first editorial adventure, somewhat tutored by the institute teacher François Couperin de Fontainebleau Robert Maggiori, from whom she had been a pupil. It was titled Archipelago of Passions and was published in France by Seuil and a year later in Spain by Libros del Zorzal.


Nicolas Matthieu, winner of the Goncourt Prize.

It is not the only artistic concern we have discovered of Carlota Casiraghi in these years. Already in 2020, while married to Dimitri Rassam, son of producer Jean-Pierre Rassam and Carole Bouquet, one of Carolina of Monaco’s closest friends, she produced her first film, which was directed by the Afghan Atiq Rahim and premiered at the Toronto festival that year. Carlota could not attend because she was pregnant with her son Balthazar.

Our Lady of the Nile was a notable adaptation of the novel of the same name by Scholastique Mukasonga, winner of the Renaudot Prize in 2012. It told the author’s childhood in a boarding school for the high society of Rwanda in the 1970s. It was a period when the genocide that would shock the world two decades later was beginning to brew.

Carlota Casiraghi has always loved surrounding herself with people with great intellectual pursuits, such as her current partner, the writer Nicolas Matthieu, winner of the Goncourt Prize in 2018 for the novel His Children After Them, which has also known a notable film adaptation. Matthieu, from a humble family, has worked very hard to secure a privileged position in French letters.
