Providing the first introduction to the key scholars, theories and debates in trans studies, Transgender Theory is an expansive and inclusive contribution to a nascent field. Each chapter offers a distinct and interconnected perspective on the various intersections of transgender lives and struggles around the world. From its prehistory (before the term transgender was common currency) through to the latest scholarship, the book provides a comprehensive and up-to-date overview of trans scholarship. The narrative is deepened through the co-authors' (one a trans woman the other a trans man) personal perspectives and insights on being trans / becoming woman and man. The book speaks directly to those who are questioning their designated gender, coming out as trans or non-binary or, like the authors, undergoing an unending process of gender transition, a transition without destination.
