This is the only book that systematically examines transgender sex work in the United States and globally. Bringing together perspectives from a rich range of disciplines and experiences, it is an invaluable resource on issues related to commercial sex in the transgender community and in the lives of trans sex workers, including mental health, substance use, relationship dynamics, encounters with the criminal justice system, and opportunities and challenges in the realm of public health. The volume covers trans sex workers' interactions with health, social service, and mental-health agencies, featuring more than forty contributors from across the globe. Synthesizing introductions by the editor help organize and put into context a vast and scattered research and empirical literature. The book is essential for researchers, health practitioners, and policy analysts in the areas of sex-work research, HIV/AIDS, and LGBTQ/gender studies.
