Hate to be a naysayer, but there are at least as many very successful independently published books that have apparently never been properly edited as there are independently published and professionally edited books. This is especially true for nonfiction, although true in varying degrees for fiction, too. Our subsidiary company provides a range of services for micro- and self-publishers, but I would never allege that our editing will create success for anyone's book. Don't get me wrong. I believe every book should be professionally edited, but that editing will not -- in and of itself -- lead to success. Editing is necessary, but marketing is king. If you can only afford one, best to spend your money on marketing.
