This book explores the life and impact of Chevalier d'Eon, an historical trans figure in eighteenth-century France and Britain. Drawing from archival research and Deon's memoir, the author provides a comprehensive picture of her role in trans history and culture. He argues Deon's adoption of multiple voices and genres is seen, not as evasiveness or postmodern gender play, but as a trans-affirming celebration of "the intertextual possibilities of the transsexual body." He further posits that no trans woman has left us such a large archive of life writings, or lived her life on such an epic scale, and we can therefore construct a different way of telling trans lives and leave room for possibilities that we haven't been presented with yet.
