Both versions are now available in paperback, exclusively at Amazon.  There are new links posted at each version's page on our site to take you directly to the paperback edition.  List price is $12.99, and as soon as Amazon properly links each paperback with its e-book version, I think you'll be able to get the Kindle version free when you buy the paperback -- assuming I set it up properly.
