David's a friend. He's also a phenomenal writer. I have been floored by the quality of his work though I admit it's a style that won't appeal to everyone. Fortunately for wannabe writers out there, he is now doing freelance editing. If you're interested, he will do a free edit of fifteen pages for you, returning them by regular mail. If you like his work, you can discuss rates. He's very, very good. Tell him "Curtis" sent you (no, I don't get a cut).
Beyond that, I can't say any more. David's a very private individual (and no, I'm not David).
