Una Lucha colectiva tells the life story of Lucía Castro, and explores her involvement in the fight against bank foreclosures in the last decade of the twentieth century and in the defense of women's human rights in the first two decades of the new century. Lucía's life is narrated partly by her son and daughter, but mostly by many of the women, and some men, who met her as they became involved in organizations such as El Barzón, founded by indebted farmers at risk of losing their land, or the Centro de Derechos Humanos de las Mujeres, which works with mothers seeking justice for daughters who have been victims of feminicide. Each contributes a vignette describing the impact Lucía had on their lives. The result is neither biography nor autobiography, but a multivocal mosaic portraying the collective experience that emerges from these struggles. The book also includes various writings by Lucía, including autobiographical texts, speeches, and articles. In one of them, she describes herself as a lawyer, a feminist, and a theologian, bringing together in her worldview and political practice the different strands that make up the tradition of popular protest in Mexico.
