Chinese extremists want to destroy America—and now they've got the means to do it.
When a rogue Chinese general threatens to unleash a biological Armageddon across the U.S., there's only one man who can stop him: the Spartan. Tier One's toughest soldier has just seven days to prevent China's toughest special forces soldiers from detonating their plague canisters across the United States, poisoning millions and sending the world teetering towards war.
By the Spartan's side is Teresa Vasquez—a former Juarez policewoman whose family was murdered by the cartels. Vasquez is now the owner of the world's first invisibility suit, after joining forces with the formidable Colonel Garin, Homeland Security's top troubleshooter and the Spartan's mentor.
Besides the terrorists, standing in the Spartan's way is the mafia, the Mexican cartels, the triads, U.S. special forces … and one vengeful U.S. General who never forgot the recruit who refused to salute his superior.
The race is on for the Spartan to stop the canister conspiracy and save the world before the bombs go off on the 4th of July … or before his enemies can kill him.
