It's done! Journey to Angkor has been published as an ebook on Smashwords, where you can get it in formats for Kindle, Stanza/ePub and many other popular reader formats. Follow this link to get to the Smashwords page for the book.
I'm willing to give away copies of the book to anyone who promises to provide a review on Smashwords or on their own blog. Leave me a comment if you're interested.
