Meteors too small to detect bombard Earth's major cities. When the smoke clears and first responders begin to search for survivors, but the living dead are what they find. They're not just zombies. Detached body parts are moving on their own, sticking together, and forming something else. Something... bigger.

     Twin teenaged brothers who couldn't be more different. Marcus, the loud, cocky high school athlete who's fawned over by all the women, and Jacob, the round body, uncoordinated gamer who's only known by surprised association with his twin.

     The world is at war, but with what?
