Kindle Direct Publishing has provided an opportunity for independent authors to compete on a level playing field with the giants of the bookselling industry, Locke said in a press release. Not only did KDP give me a chance, they helped at every turn. Quite simply, KDP is the greatest friend an author can have.

Literally every week the past few weeks, someone new joins the Kindle Million Club.

Locke's sales are just as dynamic. He writes on his website, Every seven seconds, 24 hours a day, a John Locke novel is downloaded somewhere in the world.
