Doubleday published their hardback edition of I SWEAR: My Life with Tourette’s by John Davidson on 21 August 2025.
“Funny and heartfelt … this skillfully told tale deserves praise for how it lets us non-sweary people see inside the ordinary, albeit anxious, mind of someone with Tourette syndrome.” The Times
“An astonishing tale about an amazing man. If this book were given out to schools it would triple the empathy levels for Tourette’s.” Jo Jo Moyes, author of ME BEFORE YOU and SOMEONE ELSE’S SHOES
John Davidson’s life inspired the heart-stopping film I SWEAR, to be released in the UK on 10 October 2025 starring Robert Aramayo, Shirley Henderson, Maxine Peake and Peter Mullan.
