How do you change the world? Meet Léa, polyglot, labour activist, farbrente feminist. Born to a large Jewish family and raised in a French Catholic town, Léa moves fluidly between languages and cultures. Her search for meaning and her instinct for justice place her at the centre of the great changes of the 20th century. From street fights in Berlin to protests in Montreal, she defies the expectations and limitations of women’s lives, wins historic victories for the union movement, and grapples with her own convictions. Based on the life of famed activist Léa Roback, this novel brings to life a heroine emboldened by political struggles that resonate to this day.
