When Period. End of Sentence. won an Oscar in 2019, the film’s co-producer and Executive Director of The Pad Project, Melissa Berton, told the audience: “A period should end a sentence, not a girl’s education.” Continuing in that revolutionary spirit and building on the momentum of the acclaimed documentary, this book outlines the challenges facing those who menstruate worldwide and the solutions championed by a new generation of body positive activists, innovators and public figures. Including interviews from people on the frontlines—parents, teachers, medical professionals, and social-justice warriors—Period. End of Sentence. illuminates the many ways that menstrual injustice can limit opportunities, erode self-esteem, and even threaten lives. This powerful examination of the far-ranging and quickly evolving movement for menstrual justice introduces today’s leaders and shows us how we can be part of the change. Fearless, revolutionary, and fascinating, Period. End of Sentence. is an essential read for anyone interested in empowering women, girls, and others around the world.
