Survivors live underground, ever on the defensive against rotters -- mindless corpses that troll the sweltering surface. A new menace has evolved, set on human annihilation.

     A zombie outbreak that will put his endurance skills to the test. It was just another training day for Niles. Getting ready for a one-hundred-mile footrace takes dedication. Twenty-five miles into his run and Niles is faced with the unthinkable. A campground overrun. People dead. Corpses reanimated, eating the living. With his skills and training, Niles could outrun the zombies. But when he stops to help two hunters, he needs to slow his pace and teach them to run. Can endurance running be taught on the go? Will they make it out alive? Dawn Patrol is the prequel to the Undead Ultra series.
