New book on John Wayne - He wanted to direct and not act.

The book is based on an incomplete memoir found in John Wayne’s papers.

I found the book on Amazon. But it’s not available in Kindle. That’s really weird for a newly published book. The hardcover is high priced. I haven’t decided yet if its worth buying. I need to learn more about the author first. I see Michael Goldman also wrote a book on Clint Eastwood.
