I've already published two of my novels, Kirk's Landing and Return to Kirk's Landing. You can buy print or ebook copies from Amazon, Chapters, Ingram-Spark, Smashwords, iBooks, Kindle, etc. Or perhaps find a copy in your local library. I've also written over 100 quick little Flash Fiction stories over the years, all up here on my blog.
I'm thinking of doing a podcast of these - maybe a chapter a week, or a story a week, or both. Free of course. I'm told I have a good 'radio voice' so would do these myself, using my headset mic and Audacity and SoundCloud. Nothing too fancy. If it works out, I'd get better equipment, redo/repackage, and sell as audio books.
