FILE - In this May 13, 2013 file photo, author Dan Brown poses for a portrait in New York. His new book, "Inferno," published by Doubleday released on May 14. No mega-sellers came out in 2013, nothing that compared with E L James' "Fifty Shades of Gray" or Stieg Larsson's crime novels. Adult readers turned to dependable favorites such as Dan Brown and Khaled Hosseini, while teens and grade-schoolers stuck with Rick Riordan, Jeff Kinney and Veronica Roth, whose "Divergent" series is set to debut on the big screen in 2014.
