I never knew who Styx was in real life either and had no idea that he published books. He found a niche market. His books are very cheap. Most of them are $1.50 to $2. I'd like to read his book "After the Ashes" and other ones. He really is an interesting guy.
I was reading his bio on Amazon and definitely love this picture of him. I think it might be a self-portrait he did himself, maybe with pastels. It really captured his aura, IMO.
