Turncoats is a shot in the arm of professional discourse. Many public panel debates are dry, tepid and risk-averse, unable to dig into imporant issues for fear of causing offence. In response, Turncoats fuses theatre with argument to create playful and combative format designed to ferment permissive and critical discussion.

Phineas founded Turncoats in London with Maria Smith in 2015. It now has multiple chapters around the world led by indepent agitators.

The youth movement Woodcraft Folk has made a remarkable impact on British politics and education. Founded in 1925 on a wave of post-WWI utopianism and now a network of hundreds of local groups, it has empowered thousands of young people to shape the world around them.

This book explores the history, values and evolution of this unique organisation in a chronological sweep of stories from hand-making tents, and rescuing children from advancing Nazi troops, to campaigning against climate change.
