Newsweek: "Boyd Morrison was finishing a Ph.D. in industrial engineering when he wrote his first novel. Five agents rejected it. Nine years later he tried again, and this time he did get an agent—after nearly three years and three novels. But that turned out to be some kind of cosmic tease, because 25 publishers turned down The Ark. With nothing left to lose, Morrison uploaded The Ark and his two other unpublished novels to Amazon’s Kindle store in March 2009. Within three months, he was selling books at a rate of 4,000 a month—a number that attracted the attention of the same publishers who had rejected him."
Bravo. Note that Thoreau, Whitman and Virginia Woolf are among the writers who could tell similar tales, though without the digital element, of course.
