The authors have made adequate time for Indigenous and Two Spirit identities and people. Talking about decolonizing the gender narrative in a way that traces back to the very roots of the first peoples in a place is something that is crucial in providing understanding, but is often ignored or overlooked. Hands down, I will recommend this book for anybody looking to learn more about gender and sexuality. It's an amazing resource for ALL, regardless of identity, experience or knowledge. I fell head over heels with this book, and I can't wait to shout it from the rooftops!--Katrina Werchouski, Director of Indigenous Cultures Center, Northland College

As a trans masculine person [...] I identified with so much, over and over again. Not only did this validate my own journey but it offered me access to the joys and difficulties of others and I felt less alone. This book will travel with me, it's not a one off read, but a guide I can dip in and out of whenever I feel the need.--Wenn Lawson, author of Transitioning Together

How to Understand Your Gender is a practical entry level guidebook for people who wish to challenge gender binarism, and should contribute to binarism's ongoing evolution.--Jane Haile "New York Journal of Books"
