Right move

Happy to write that http://www.amazon.co.uk returned my book: Vil Mirzayanov. State Secrets:An Insider's Chronicle of the Russian Chemical Weapons Program to it's category Biological&Chemical. Right now my books sale's rank is not so good but in this category it is no. 12. It was some time even no.2 which is not too bad for self-published author. My competitors definetly have an advantage because their publishers openly promoting their books. My advantage is very clear: I am specialist who worked 26 years in this area. Almost all authors in category Chemical Weapons are not specialists in this particular area and writing what they learned from other sources creating books about books.
