Vengeance promotion huge success; a 538 ranking out of millions of kindle books in a single night
I was curious to see what the interest level was out there for aviation books in general and WWII in particular. Going that high, that fast; proved to me there is still a deep interest in aviation. 538 out of all kindle books; #1 on Aviation BSL and #16 on Historical Fiction. Good news for all aviation writers I would think.
