George Zaragoza just wanted to go to work and teach. But now he must face a horrific new reality: reanimated corpses attacking and devouring the living, federal agencies and military run amok, and an unpredictable civilian population surviving on their own terms.

Southbound I-35 was once the road he took to work. Now it is a bloody trail of bodies, wreckage, and woe standing in George's way. But before George can get home, he must come face to face with a ghost from his past, a vicious truth that could prove to be his undoing.

Can George survive the obstacles on southbound I-35, FEMA and Homeland Security, and the army of flesh-eating zombies on the verge of exterminating humanity as he travels down the road?

Around the globe, the dead are rising to devour the living. Hospitals are overrun, and martial law has been declared. The streets are in chaos. Society is disintegrating.

In a small south Texas town, the mayor has rallied his citizens against the living dead and secured their borders. Isolated in the countryside, the community holds their own. But when two strangers from San Antonio stumble into town, they bring news of a global peacekeeping force sweeping toward the city. Led by a ruthless commander, the force is determined to secure the republic of Texas on its own terms, and establish a new, harsh government for the plague-ravaged nation.

Will the independently fortified Texas town hold out against the flesh-eating zombies and the tyrannical foreign army traveling down the road?
