Hiya,
To be honest, I'm trying to see how I can reignite the plot for this. It's taken me some time to think on plot points for the story (I lost the manuscript remember). So, I am seriously considering incorporating the contents of this story into the one I am currently writing called Far Beyond Your Reach.
If I do however, my current story won't act as a sequel so I won't be referencing The Shadow Guy. I might rewrite and clean up any mistakes in the Shadow Guy and make it stand alone story with added content since it's been years when I wrote it.
This isn't a final decision but the most likely course of action. I'll to know your thoughts on it. Feel free to check out the story I have currently in writing (Far Beyond Your Reach) and see you soon.
