The Mexican cartels are desperate. Since the secession, their human trafficking business has dwindled while the presence of military units along the border makes smuggling a far less lucrative proposition. Like a pack of starving predators, the massive criminal organizations turn on each other, preparing to unleash a bloodbath unlike any the world has seen.
Out of the chaos rises a new leader, a man whose reputation for strategic thinking and meticulous planning is known throughout the underworld. He has a plan to overthrow the government in Mexico City and bring the cartels into a new era of dominance and profitability. Best of all, he will make it look like Texas is at fault.
Zach and Sam are thrust into the middle of the diabolical scheme, the two Rangers fighting for the very survival of the republic and all she has come to represent.
