“I devoured this essential history of the people and campaigns that turned Britain into Terf Island in a single sitting. Packed with sharp insights and telling details, this is social history written with the thrill and verve of a whodunnit.”

Helen Joyce, author of Trans: Gender Identity and the New Battle for Women’s Rights

The United Kingdom has been labelled Terf Island – sometimes affectionately and sometimes contemptuously – for its successful resistance to transgender ideology.

This is the story of the brave and determined women who led the charge against trans activist demands which undermined their rights and jeopardised the physical and mental health of children. They dragged shadowy campaigns into the daylight, exposing the harm that would result, and the harm that had already been done. They forced policy change, set legal precedents and changed public opinion.

Fiona McAnena has been right there campaigning with them. Her unique insight and personal involvement brings to life the intimate human stories behind the movement to Keep Britain Terfy.

This extraordinary, inspiring, furious and sometimes funny account shows how a few women acting on their convictions turned back a tide which threatened to sweep away the rights their foremothers fought for.



“When historians chronicle this period of insanity, due honour will go to the four heroic women whose stories are told in this engaging and important book.

“It’s easy to talk sense now that the tide has turned, but it took real courage in the days when you could lose your job, suffer savage bullying and almost universal ostracism, even physical violence, simply for stating a scientific fact.”

Richard Dawkins FRS, Emeritus Professor of the Public Understanding of Science, University of Oxford
