This inclusive, unapologetic, and humorous guide to menstruation quashes stigmas and provides us with the latest research and information on periods.

Filled with information and free from cultural hang-ups, this gender-neutral book is directed at anybody thats ever dealt with having a period. Writer and influencer Tara Costello has been writing about menstruation for more than a decade and, here, she pulls together her research and experience into a book thats wide-ranging, inclusive, and fun.

Boldly illustrated by Mary Purdie, Red Moon Gang tackles every aspect of the menstrual cyclefrom the biology and science behind why you bleed every month, to the latest findings on hormonal fluctuations (aka, why youre PMSing so bad). It takes a deep dive into the different types of menstrual products available, including their pros and cons, and covers various period conditions such as endometriosis and polycystic ovary syndrome.

Drawing from her own experience, Costello explores how having a period shaped her relationship to her body and her place in the world. And she discusses topics that arent generally covered in health class toosuch as how periods are a particular challenge to those experiencing body dysmorphia, individuals living in poverty, and disabled people. Finally, she offers up a Period Toolkit, listing products and retailers she loves, tips on how to make menstruating easier, and resources for further education.
