Camille,
Sorry, I can be thick as a brick some days.
NOW I understand!
OK, I gave it away as a free download at my site as PDF originally. Then I moved on to giving it away free with a coupon at Smashwords in all formats including .mobi (Kindle). I uploaded myself to Amazon rather than use Smashwords (I opted out of uploading to Amazon through Smashwords), but that doesn't mean you can't offer it at Smashwords itself.
Clear as mud?
Keep asking questions if you're interested. I'm quite happy to share everything I've done. Perhaps I should blog about it as I'm sure there will be others that may ask the same question. Mind you, I'm no bestseller, so I don't know that what I've done is really the right way to go about things.
@HRD, my book was selected at Goodreads for a group discussion over the Fantasy Book Club for June/July if you're interested. And that goes for anyone else that's interested.
Shayne/Camille, as for cross-over series, yes it's complicated to pitch that in the right way. My agent and I have had some struggles around that since editors see my book differently. It doesn't fall neatly into the fantasy genre and crosses into paranormal/thriller/horror. It's tough to sell that, but quite honestly you have to write what you love and hope that there's an audience for it. All of this could change tomorrow and yesterday's vampires will be tomorrow's angels.
