What do you do when there are no borders? When the lines you thought existed simply vanish? How do you plant your feet to make a stand when you no longer know what side you're on? The war has come home. For over forty years, Art Keller has been on the front lines of America's longest conflict: The War On Drugs. His obsession to defeat the world's most powerful, wealthy, and lethal kingpin--the godfather of the Sinaloa Cartel, Adan Barrera--has left him bloody and scarred, cost him people he loves, even taken a piece of his soul. Now Keller is elevated to the highest ranks of the DEA, only to find that in destroying one monster he has created thirty more that are wreaking even more chaos and suffering in his beloved Mexico. But not just there. Barrera's final legacy is the heroin epidemic scourging America. Throwing himself into the gap to stem the deadly flow, Keller finds himself surrounded by enemies--men that want to kill him, politicians that want to destroy him, and worse, the unimaginable--an incoming administration that's in bed with the very drug traffickers that Keller is trying to bring down. Art Keller is at war with not only the cartels, but with his own government. And the long fight has taught him more than he ever imagined. Now, he learns the final lesson--there are no borders.
