On the US-Mexico border, a bloodthirsty war is raging. Drug cartels - including perhaps the most violent and highly trained in the world, Los Zetas - are rampant, butchering and killing thousands of victims in the most obscene ways imaginable.

When the CIA reaches out to the British military for help, SAS legend Danny Black and his team are despatched to give the Zetas a taste of their own medicine. Working under the radar, their mission is to sow death and mayhem among the cartel, and to coax out from hiding their elusive leader, Z1.

But as Danny is about to find out, the cartel's arm is long, their sickening strategies underhand and brutal. And in the dog-eat-dog world of this dirty war, nothing is ever quite as it seems. It will take all the SAS team's skill to break through to the heart of the cartel. And even that might not be enough...
