An excellent guide to Amazon, I think this book would be useful to both new and establish authors possibly slightly more useful to new authors as it starts with the basics like how Amazon really works. I particularly like the useful lists that are included in the book. Such as lists of useful reviewers, hashtags to use and many many more other handy tools for authors. I will be recommending this book to a lot of my indie author friends. Fab and more importantly practically useful read.
