The Cartel is second thriller novel in The Power of the Dog Series by Don Winslow, published in 2015.
It’s 2004. Adán Barrera, kingpin of El Federación, is languishing in a California federal prison. Ex-DEA agent Art Keller passes his days in a monastery, having lost everything to his thirty-year blood feud with the drug lord. Then Barrera escapes. Now, there’s a two-million-dollar bounty on Keller’s head and no one else capable of taking Barrera down. As the carnage of the drug war reaches surreal new heights, the two men are locked in a savage struggle that will stretch from the mountains of Sinaloa to the shores of Veracruz, to the halls of power in Washington, ensnaring countless others in its wake. Internationally bestselling author Don Winslow’s The Cartel is the searing, unfiltered epic of the drug war in the twenty-first century.
