Red Moon Gang is the period book a lot of us wish we'd had growing up. Written by Tara Costello and illustrated by Mary Purdie, it's a funny, honest, and research-backed guide to menstruation that doesn't talk down to you or leave half the population out. Whether you're newly navigating periods or just looking to fill in the gaps left by traditional health education, this book meets you where you are.

Costello covers the full picture: the science behind the menstrual cycle, hormonal shifts, common conditions like endometriosis and PCOS, and a practical rundown of menstrual products. The writing is clear and accessible without being clinical, and the gender-neutral framing means it actually reflects the range of people who experience periods.

Educator's Note

This book is a strong recommendation for transmasc and nonbinary readers who menstruate and have historically been excluded from period education. Its gender-neutral language and inclusive approach make it an affirming resource.
