Graham Brown grew up in Illinois, Connecticut, and Pennsylvania, moving often with his family. As far as he knows they weren't in the witness protection program or part of any top secret government agency, but then, would they really tell him? A former pilot and lawyer, and later part of a start up health care firm, Brown decided he hadn't had enough different careers yet and decided to become a writer. A huge fan of Clive Cussler, Michael Crichton, Stephen King, and television shows like The X-Files and Lost, Graham's first novel, Black Rain, debuted in January 2010. He now cowrites the NUMA Files series with Clive Cussler. Their second collaboration, The Storm, debuted at #1 on the New York Times Bestseller List.
