Raynor Winn’s memoir The Salt Path was a bestseller and literary phenomenon with millions of people captivated by this true story of financial ruin, terminal illness, and healing through nature. Raynor Winn has since published two more books and The Salt Path has been adapted for the big screen, starring Jason Isaacs and Gillian Anderson.
