From the bestselling author of the acclaimed The Power of the Dog comes The Cartel, a gripping true-to-life epic, ripped from the headlines, spanning the past decade of the Mexican–American drug wars.

It’s 2004. DEA agent Art Keller has been fighting the war on drugs for thirty years in a blood feud against Adan Barrera, the head of El Federación, the world’s most powerful cartel, and the man who brutally murdered Keller’s partner. Putting Barrera away costs Keller dearly – the woman he loves, the beliefs he cherishes, the life he wants to lead.
