When the documentary film "Period. End of Sentence." won an Oscar in 2019, the film's co-producer, Melissa Berton, said in her acceptance speech: "A period should end a sentence, not a girl's education." Now comes a new book that follows-up on that goundbreaking movie, a far-reaching book that outlines the challenges confronting those who menstruate worldwide and the solutions being offered by a new generation of body-positive activists and innovators. Our guest is the author of this work, Anita Diamant. As was noted in this starred review in Booklist: "[A] scorching and utterly unforgettable read.... Brandishing a stunning array of statistics and sharing stories from around the world of girls and women in every social circumstance, Diamant delivers a withering account of how menstruation has led to humiliation, threats, and on more than one grim occasion, even death.... This is a barn-burner of cultural analysis that never strays from the preventable suffering at its core. A life-improving title that should be made as widely available as possible."
