I wasn't sure if I would go back to this world when I first published. I didn't think that more than three people would ever read it and I didn't want to get my hopes up by planning a series of books that only I and the two friends I have who I bounce ideas off of would ever read. But I liked the set up and had some vague plans for other stories that I could tell with it.
In between writing other stories I started to cobble together a short story. I had the idea that I'd write a few short pieces set in the SI world and put them together in a collection. I even had the title picked out -- Shrink Inc: Short Subjects. (I know, I have a problem with puns. I'm in a 12 step program.) I'd finish one thing and write a bit of the Shrink Inc story. I had the plot bouncing around in the back of my head all the time. Adding things. Tweaking them. The short story became a novelette. Then the novelette grew into a novella. When I finished my last book and went back to my short story it was now a novel.
The second Shrink Inc book is now live on Amazon. I hope you enjoy it.
