In this straightforward nonfiction title, Subramanian offers a detailed guide to menstruation and stresses the importance of teen readers’ being informed—from learning the vocabulary to talk about their experiences to knowing how to care for themselves throughout their cycles—and able to advocate for themselves (and others). What sets this book apart from similar guides is the exploration of how menstruation intersects with identity: In chapters focused on topics including culture, gender, neurodiversity, disability, and body size, Subramanian encourages readers to consider how their identities shape their experience of menstruation. Refreshingly, the author models gender-inclusive language, using the term menstruators and asserting that “all menstruators are not women, and not all women are menstruators.” They draw on experts as well as their own experience as a queer, nonbinary Indian American menstruator, to address social issues that relate to menstruation, like period poverty, capitalism, reproductive rights, and environmentalism. The book contains plentiful guidance on topics like choosing the right menstrual products and navigating healthcare. Subramanian’s conversational tone makes the subjects—the breadth of which could otherwise be overwhelming, particularly given the lack of graphic design and minimal stock art spot illustrations—feel approachable. Occasional exercises offer readers opportunities to reflect and interact with the content. The combination of well-researched information and practical advice for young menstruators makes this a welcome addition to the literature.
