Top critical review
Chris Voss is an impressive guy, BUT..
Reviewed in the United States on April 26, 2017
The book is roughly is 60% war stories, 20% sales pitch for the book and courses and only 20% how to. Starting on the very first page it tries to make you believe Chris's son has been kidnapped, then reveals it's just a scenario at Harvard, which sets the tone early.
Rather than spending your money and time on this book, I would suggest taking a look at Voss's YouTube videos, he says everything in the book in less than 10 min across a few different vids, minus all the war stories, and you get more out of it, because you hear his tone and the way he puts things.
Read the whole thing, was a bit disappointed, promises the world until the last page, but doesn't really deliver.
