American Kingpin: The Epic Hunt for the Criminal Mastermind Behind the Silk Road is an account of how Ross Ulbricht built the Silk Road, a marketplace for illegal drugs (the book several times compares it to “Amazon for drugs”).
It traces the history of how he built the site, and how individuals from several branches of law enforcement collaborated (or competed…) to stop him.
I thought the technical explanations were very good: accurate so a geek like me didn’t get annoyed or frustrated about incorrect descriptions, and short enough to be relevant and informative to others.
Overall I highly recommend it.
