I am now officially half way through working on my second draft. I also have a line editor working on the book concurrently, so good progress is being made. I have to say, seeing some chapters again as a "reader" I personally love the book. It's fun, interesting, and thought provoking. I am biased, I understand, but this is the book "I want to read". And that was my goal.
So I think I am on target for a final draft in July. The time from then to publication is still foggy, since I am lining up "beta readers" to look through for any continuity issues. I don't know how long that will take.
My tentative goal was to have Print On Demand ready to go by September so I could man the booth at the Big E. But that is going to be tight. Cross your fingers.
