What happens when, aged 30, you realise you're transgender? This was the question that confronted Yves Rees, a historian whose life was upended by gender transition in 2018. Then known as a woman called Anne, Yves was forced to grapple with the sudden realisation that they were not, in fact, female at all. But did this realisation mean that Yves was a man - or something else altogether? When you've lived a lie for so long, how do you discover who you really are? And how do you re-learn to live in the world as a different gender? This book follows Yves on their raw journey of re-becoming, telling a transmasculine transition story that digs into the messiness of bodies, gender and identity. It brings to light the challenges and joys of being transgender in Australia today, and reveals how much trans experience can teach all of us about what it means to be man or woman?
