Whether literature offers solace or confusion, whether it shows the way or disorders, every writer must have been moved in the course of his or her life by a passage, a line, an image or a poem which gave direction to his or her life. Was it a boys' book? A text on a tile? A column? Or rather that highly valued, often quoted passage from world literature? Jonathan Safran Foer, Tash Aw, Ramsey Nasr, Joke van Leeuwen and Petina Gappah read those passages that changed their lives for good, and reveal what happened to them when they read those lines for the first time. The programme starts with a reading from his work by the Iranian author Shahriar Mandanipour.
