Charlotte Casiraghi has written a book in collaboration with her former philosophy professor, Robert Maggiori. Titled Archipel des passions, it was published by Éditions Seuil on February 19.

Princess Caroline’s elder daughter is a graduate in philosophy and founding member of Monaco Philosophical Meetings. Charlotte has dedicated the 336-page book to her father, Stefano Casiraghi, who died in a motor boat accident in 1990 when she was only four years old.

The granddaughter of Princess Grace co-authored the book – whose title refers to fiery passion which can create fertile ground from its destructive forces – with Robert Maggiori, a philosopher and literary critic at Libération newspaper.

Maggiori was also Charlotte’s philosophy professor at the François Couperin high school in Fontainebleau. In an interview with ELLE, he described his former student as someone endowed with “an incredible perfectionism”.

Archipel des passions is available for €20.
