Devil's Mark

Trouble on the U.S. border with Mexico puts Mack Bolan in the middle of a DEA counter-narcotics operation that's been compromised in the worst way. The mission takes a bizarre and unexpected twist when headless corpses from both sides of the cartel wars indicate a new player has entered the game. The mysterious figure is spoken of in terrified whispers as "The Beast." All knowing, all seeing, his ruthless henchmen appear out of nowhere, spreading slaughter and commanding deathly silence.

Bolan has seen enough evil in the world to know monsters exist—but in his experience they are all too human, preying on the innocent and the weak. And he is determined that whoever or whatever is behind the biggest coup of Mexico's drug trade will face his retribution.
