Dozens of Turkish journalists now languish in Turkish prisons because of this government's desire to control the press and the flow of information. For example, Ahmet Şık, a journalist who wrote a book entitled Imamın Ordusu (The Imam's Army), has been in prison for over a year. He was arrested before the book was even published.
Dan Brown, the author of the Da Vinci Code, is extremely popular in Turkey as many people there believe that the Vatican is the nexus of all evil, and are happy to see Christian values undermined. This says a lot about the predominant paradigm, doesn't it? Still, as a person who loves Turkey and the Turkish people, it is difficult to imagine why a work of fiction would be perceived as a threat, especially when the novel says so many good things about the country and their culture.
