This a well written and well researched true story of how a security chief inside the Cali drug cartel came to turn into a DEA informer who provided law enforcement with the inside information required to bring down the cartel.
The author is/was a reporter for the Los Angeles Times and his research for the book seems accurate and extensive. His writing style is well suited to the spoken word and the audio book narrator does a very good job with the material.
It's a fascinating story.
I have a 40 minute highway commute to and from work and I generally pass the time listening to audio books. I thoroughly enjoyed this one.
