ATF agent Sean Ozburn is deep undercover, supporting the sicarios of the North Baja Cartel, when he suddenly goes completely dark, leaving Charlie Hood and the support team from Operation Blowdown with a safe house full of bodies and no explanation. Sean's only communication in the following days consists of a series of haunting digital videos sent to his desperately worried wife, Seliah.

As he pieces together evidence of his friend's strange quest and searches the border landscape, following faint signals to the man's whereabouts, Charlie Hood must determine if Oz is simply chasing demons deeper undercover than anyone has ever gone, or whether his friend has suffered a permanent break with his mission and his moral compass.

A crime novel of unprecedented scope and unrivaled storytelling ambition, The Border Lords revisits the fevered landscape of America's southern border--and confronts the unexplored depths of humanity's dark soul.
