The Cartel Lawyer [EPUB ebook] 

Dr. Jason White and Ricky Gold, a former professor and defense attorney in New York City, find themselves blacklisted from their professions after Jason is denied tenure and Ricky is disbarred from the legal profession.
Desperation leads the two to start working as consultants for a new Mexican cartel. Soon, their academic prowess helps the cartel make millions of dollars, and the criminal organization expands its operations and revolutionizes the way business is conducted in the criminal underworld through data science.
Meanwhile, DEA agent Pedro Gómez is seeking to bring the cartel and its associates down. After he learns that White and Gold might have something to do with the criminals, he begins to dig deeper into their affairs. As the net tightens around them, how far are the two willing to go to survive?
