What do you mean by USA not experiencing a recession or stagnation? What about recent collapse of the stock market, which was experience due to predictions coming from the U.S. - inflation and recession exactly?

As for the book - it's hard for me to say, but I'm not convinced that the author is trying to sell us anything. Especially since, as you can see, the website doesn't have it yet. But if you switch to the Polish version (because the author is from that country, I think) you can see that the book is published for free and you can optionally donate money to some organization (I think taking care Bleeding Disorders).
