My New Book is Presently Ranked 2nd On Amazon

Those of us who have written books know how it feels if they have a modicum of success, and are quite happy about it. On Amazon in the "Atheism" category, the Kindle version of my new book, The Outsider Test for Faith: How to Know Which Religion Is True,is presently ranked 2nd place, or 7,000th over-all. It most likely won't stay there, but it sure is nice to see. What I can't figure out is how many books this represents.
