A young woman follows in the footsteps of her deceased father, who led a secret second life that her daughter never knew about. Writing, she approaches this stranger and at the same time sheds light on the dark corners of Italian history: Marta Barone is less than thirty years old when her father dies. Her mother finds a file with documents relating to a trial in which he was accused of being a member of a radical left-wing movement. And suddenly nothing is as it once was: who was her father really? This strange young man, Leonardo, who was always on the side of the defeated, the doctor from the working class who fought wherever there was someone to save and who was sentenced to prison as a member of an extreme left-wing group - why had he never spoken to her, his daughter, about this? Testimonies, memories and revelations slowly come together to form a delicate portrait of a contradictory man who lived in a turbulent time. The streets of Turin are the scene of daily political struggle, and Marta Barone's novel is an urgent attempt to understand: Who were these militant communists? What did they believe in? And what remains of their struggle a generation later? This autofictional debut is an extraordinary testimony to the times and a moving exploration of her father's secret life.
