I think the best, or at least the easist, marketing you can do yourself for a book is to do what is necessary to get lots of five-star reviews. Toward that end, I was on a site that charges $20 a month for the privilege of reviewing books. The functionality was approximately what I've created here. Here, it's free for everybody. And I might even have some fun.
I see the blue book icon indicating you have a featured book. Please do list it on the pub. Go to Free Amazon Reviews for Your Featured Book and select Request Reviews in the menu.
I hope that after you list your book, you will also review somebody else's book.
