In 2006, Roberto Saviano shook up all of Italy with his book about the Neapolitan Mafia. "Gomorrah. Journey into the Realm of the Camorra" hit like a bomb. It served as the basis for a feature film that won an award at Cannes. Saviano’s novel broke the Mafia’s vow of silence, but he paid a high price for it: The author has been living under police protection for 20 years.
