This a historical novel set in Italy and France during the early decades of the last century, with the young woman who gives the book its title as the protagonist. Fresh out of adolescence, Giulia leaves her family of bourgeois ambitions, who live in Savona, to have an adventurous life alongside the man she fell in love with, the journalist and writer Trento Tagliaferri, an anarchist militant.
In Milan, Giulia begins to associate with leading figures of Italian anarchism, such as Errico Malatesta and Armando Borghi, and becomes friend with women who marked this vibrant current of the European left, such as Leda Rafanelli and Maria Rygier. Alongside Trento, she fights for a revolution that would never come to pass and confronts fascist violence. Persecuted by Mussolini, the couple goes into exile in Paris, where Giulia dedicates herself to fulfilling her professional dream: designing and making women's hats. In the French capital, she meets with major names in fashion, such as Coco Chanel, Pauline de la Bruyère, and Elsa Schiaparelli, and experiences the artistic effervescence of the 1920s. Giulia also spends a year in Brazil, where Trento moves to engage in political agitation.
