Amazon just announced something called an "author ranking." I'm #4,282. When I looked into it, I found it is based on just one of my books so, if both books were included, I might be, oh, in the 3,000s somewhere.
While attending the National Weather Association's annual meeting in Madison, WI earlier this week, I found there were many meteorologists who have enjoyed both When the Sirens Were Silent and Warnings.
So, if you are looking for a good book, please check them out. Let's get that ranking up there, people!
