Our Red Book takes us through stories of first periods, last periods, missing periods, and everything about bleeding that people wish they had been told. Weaving together powerful voices—from teenagers, midwives, Indigenous scholars, Olympic athletes, incarcerated writers, disoriented fathers, elected leaders who fought to make period products free, friends transitioning genders, grandmothers, and lovers—the book invites us on a collective journey of growth and change, with Rachel’s own voice as a guide.
