'The field of "transgender" and "transpositionality" has been carved out as a new field of inquiry in the past decade, showing the fragmentation and diversification of masculinities and feminities - along with the error of any sharp polarisation. Dave King and Richard Ekins are the leading world sociologists in this field and have mined it richly since the 1970's. The book brings together a brilliant synthesis of history, case studies, ideas and positions as they have emerged over the past thirty years, and brings together a rich but always grounded account of this field, providing a state of the art of critical concepts and ideas to take this field further during the twenty first century. This is a must read for all interested in this new area of inquiry ' - Ken Plummer, Professor of Sociology, University of Essex. Editor of Sexualities. Author of Intimate Citizenship 'An outstanding survey of the evolution of trans phenomena, splendidly written, highly informative, scholarly at its best, yet easy to read even for those neither trans nor sociologist.Drs Ekins and King, experts in the field, unroll the panoramas of sex, gender, and transgendering that have evloved during the last decades.
