I recently did a pair of guest posts on the wonderful blogs of Craig Saunders and Ken Cain. The essay is called The Genesis of People of the Ethereal Realm, done in two parts. Below are links to each post, and while you're there be sure to peruse the rest of their blogs. A lot of good stuff there.
Part one, dealing with how I came up with the idea for People of the Ethereal Realm, is available HERE.
Part two, detailing what I learned while getting the book published in the small press, is available HERE.
