So did I.
I bought the Kindle ebook version. At the same time, I bought the Audible audio book version. When you buy a Kindle version you can buy the Audible version for only a couple of dollars more. It is great for listening when you drive.
If you buy a conservative book at a brick & mortar store it will somehow never make it onto the New York Slimes best sellers list. If you buy it at Amazon it will be included in the Amazon best sellers list.
I have downloaded many conservative titles thru Amazon to my Kindle Fire. Easy as one click, assuming you’ve pre-registered your credit card. D’Souza’s book is also available in many libraries incl. many of his older titles.
