Or so says The Hollywood Reporter: http://www.hollywoodreporter.com/lists/hollywoods-25-powerful-authors-2016-931979
I seem to recall dimly that I was number seven a few years ago, so I guess I am getting more powerful by the day. Soon I will rule the world.
Actually, though... I am delighted to see so many of my friends and colleagues on the list this year. They've got Diana Gabaldon at #14, Ernie Cline at #12, Gillian Flynn at #11, Dennis Lehane at #10, Neil Gaiman at #9, and Stephen King at #2. All writers I've published, worked with, hosted at the Jean Cocteau, and just been friends with, for varying lengths of time. All amazing talents, too. As are the other authors on the list, the ones I don't know.
As to how much "power" any writer actually has, however... well, that's another question.
