The books, instead of being written by one person, are written by 50 different researchers. For every question I had, I found 3 different people to answer it. One local, one expat, one other. That way the book isn't just one person's point of view.
Then at the end, an editor combined all the different answers into one, and I went through the final-final to clean it up.
I'll write more about this soon. Good lesson learned about making a robust plan versus a fragile plan. At first I thought I'd write all 16 books myself. Next I thought I'd hire one writer per-country. But this system turned out to be a much better way to get different viewpoints.
Anyway - thanks again for pointing out the error.
