A former assassin leads a heroic band of foreign fighters to thwart an enemy like no other.
Leine Basso races to prevent Syrian intelligence from obtaining a lethal bioweapon—a savage combination of toxins never before seen in nature.
Leine's called back to war-torn Tripoli, enlisted by her former employer to train a heroic group of Isis-fighting snipers to crush the horrific threat. But there's a leak, and the Libyan operation goes terribly wrong—the bioweapon ends up in the hands of a brutal terrorist who will stop at nothing to force the West to its knees.
Are there spies in their midst? Can Leine and her warriors prevent a ruthless enemy from releasing the deadly toxin before it's too late? Or will humanity be destroyed in a cataclysmic finale orchestrated by A Plague of Traitors?
