There is nothing new in this book, but it does make a simple collection of tips for new authors to Kindle. You could find out all of the content by searching on Google but that would likely take you more time and cost you more in lost time than the price of this.
There is plenty of room to add information about the KDP Select program, using Author Central, using Shelfari and more. For that reason, I consider the book a little incomplete.
Also, as mentioned in the description (indirectly), this book is targeted at non-fiction authors. While a lot of the methods can be used by fiction authors too, there are many ideas that won't.
