Where did you get the idea for your most recent book?
It just came to me out of the blue in 2010, based on recent experiences teaching a private student, as well as stress and frustration in my life. On a simple framework, a story was fleshed out, but Version One was fundamentally flawed. Then, retaining the essential elements of the story, out of the blue, on a flight in China in early 2012, I came up with Version Two. That went through more development and many rewrites until I arrived at the final version in 2014. Hope that answers your question!
