What does it mean for men to join with women in preventing sexual assault and domestic violence? This book, based on life history interviews with men and women anti-violence activists, illuminates both the promise of men's violence prevention work, as well as the strains and tensions that inhere, both for men as feminist allies, and for the women they work with. In this moving book, the authors provide insight into the hearts and minds of men who took seriously the feminist call by making lifetime commitments as allies in the movement to end violence against women. A stellar book that is carefully grounded in the history of the feminist and anti-violence movements, it is a must-read not only for students and scholars of gender, masculinity, feminism, and the anti-violence movement, but also for policy-makers and activists working toward ending gender-based violence.
