The murder of several border patrol agents in a moonlight attack seems like an average Mexican cartel ambush...until the killers' weapons turn out to be U.S. military grade. There's a leak in the local army base, and it needs to be plugged before more ordnance trucks south--and more innocent lives are taken. Mack Bolan heads into the desert to investigate.
But when an old ally is killed in a second assault, Bolan realizes he's underestimated the threat. Whoever is behind the attack is not only smuggling weapons into Mexico, but also building a private army. And the kingpin is intent on spreading his reign of terror into America. With an unofficial war about to break out on the border, he must plan a strategic strike to take down the empire and eliminate all its key players. And this time, for the Executioner, it's personal.
