I'm starting on a short story that will take place between book 1 and 2 which will offer some insight into other characters. Hopefully it'll be out in a few days or so. It'll be just a few chapters, but I think you'll enjoy it.
I love writing this story from a first person perspective. I think the limited view really helps me create a better story, but I do realize that you don't get to know some characters NEARLY as much as you would if I were writing from a third person omniscient view. This short story will shed some light on things going on around Alex that you may not have seen in the book.
I also got back the final edits from Tenderloin today and I have sent the book off to advanced readers so it won't be long now before you'll see book 2 coming out!
