There is so much in the book that listening to this abridged version seemed cheap and I finished it feeling very frustrated. I wouldn't hestitate to buy an unabridged version. Better there is no version than something as pathetic as this.
I found it hard to concentrate and listen to the book. The pace is quite quick in summing up historical events in the oil industry. It lacks a bit of coherence and behind the scenes analysis.
This is barely related to the actual book - it took me a whole chapter to realize that the book started and it wasn't just an extract !!! No point in getting this audible if you want the full and proper story . The audible version is basically a summary of gulf / Persian oil and related politics.
