Two world-renowned novelists, from different corners of the globe, talk about why they write. Orhan Pamuk, from Turkey, is the 2006 winner of the Nobel Prize in Literature. Carlos Fuentes, who died in 2009, was one of the most celebrated Mexican authors of all time. When Pamuk was facing a prison sentence for expressing his views, Fuentes gathered a group of international literary heavyweights to intervene on his behalf.  You'll hear both authors describe how they discovered the power of literature, and how their writing relies on a combination of dreams, magic and discipline.
