James Patterson is seen at times as more machine than writer. There’s good reason for this. His advertising background; those couple dozen credited co-writers; a happy malleability when it comes to genre (romance, YA, mystery, whatever); multiple books a year; nearly $100 million in annual revenue.
All that being said, it’s helpful to remember that at one point even Patterson was a wannabe, just another unpublished novelist trying to get his book out there. From Todd Purdum’s profile for Vanity Fair:
His first novel, The Thomas Berryman Number, about a Nashville newspaperman on a murderer’s trail, was rejected by 31 publishers before Little, Brown published it, in 1976. It won the Edgar Award for best first novel from the Mystery Writers of America, but sold only about 10,000 copies…
Selling 10,000 copies of anything would be a dream come true for most authors. Still, success as a writer is never guaranteed. Even for the man who accounted for one of every 26 hardcover novels sold in the U.S. during 2013.
