The trouble with giving books away for free on Amazon and other places is that the reason you do it is because you want reviews/ratings and most importantly feedback from people.  What actually happens is many, many people download it, but I suspect the vast majority of people don’t actually read most of the free stuff they download.

So I probably won’t be having any free giveaways in the future, (especially since I want to get an editor/proofreader for the next book, and that’s likely to cost money).  I’ll only send free copies to reviewers or people who promise to give feedback.
