Four years later, a trial of Pelicot’s abusers began. Even then, we might never have known Gisèle Pelicot’s name. But in her new memoir, “A Hymn to Life: Shame Has to Change Sides,” which will be published on Feb. 17, Pelicot explains why she decided to forgo anonymity and make the 2024 trial public. That choice made her a feminist icon, inspiring women all over France to rally around her and to demand change to France’s consent laws.
