How to Shamelessly Self-Promote (Example Inside!)

One week ago today, I self-published a short 12-page story on Amazon Kindle. In celebration of that often regrettable decision, I’ve decided to put it up for free for two days.
Any reviews, criticism (constructive, please), or general thoughts about it are greatly encouraged.
From the Hollow is something that started out as an off-handed remark I made one night and ran with it. This was the result.
Enjoy. And again, anything you have to say about it, I want to hear. Don’t hold back.
