This prequel introduces a fantasy universe and a couple characters.  The universe was intriguing enough, just, that if there were more I would have kept reading for a while to see I wanted to spend some time there.  The characters, while not masterfully developed, were interesting enough, and had an interesting enough dynamic between them, that I would have liked to keep reading.  However, I see from other reviews that this prequel takes place some generations prior to the rest of the story.  I'm not interested enough in this universe, at least for now, to pick up on the story in the future with a new set of characters.  As a free down load it was worth a try, and I intend to keep an eye on this author in the future.
