Roberto Saviano, Author of Naples Mafia Book "Gomorrah", Wins PEN/Pinter International Writer of Courage Award.

Italian writer Roberto Saviano, who has lived under police protection since penning 2006 bestseller "Gomorrah" about Naples' mafia, has won the PEN/Pinter International Writer of Courage Award.

Saviano, 32, shares the award with Briton David Hare, who is perhaps best known for his work about British institutions.

Each year a British writer is honored with the PEN/Pinter award, established in 2009 by literary and human rights organization PEN in memory of Nobel Prize-winning playwright Harold Pinter, alongside another writer who has been persecuted for expressing his or her beliefs.

"Roberto Saviano took on the Neopolitan mafia, first in the novel Gomorrah and then in the film made from it," playwright Hare said at an awards ceremony in London on Monday.

"He did so at great risk to his own safety. My hope in sharing my prize with him is that a measure of recognition from PEN may, in however small a way, make his life easier."

Saviano, now living in hiding following threats to his life, sent a message expressing gratitude.

"When you feel that so many need to see, to know and to change, and not just to be entertained or comforted, then it is worth it to carry on writing," he said in a statement released by organizers.
