Now a major Channel 4 series: the true story of Rose's ten-year struggle with 'Pure O', which causes her to experience intense and intrusive sexual thoughts

Now a major Channel 4 series

Rose Cartwright has OCD, but not as you know it. Pure is the true story of her ten-year struggle with ‘Pure O’, a little-known form of the condition, which causes her to experience intrusive sexual thoughts of shocking intensity. It is a brave and frequently hilarious account of a woman who refused to give up, despite being undermined at every turn by her obsessions and enduring years of misdiagnosis and failed therapies.

Eventually, the love of family and friends, and Rose’s own courage and sense of humour prevailed, inspiring this deeply felt and beautifully written memoir. At its core is a lesson for all of us: when it comes to being happy with who we are, there are no neat conclusions.
