A phone call to his sister leads Flex Sheridan into a nightmare and a quest to save his family from a new, horrifying epidemic that's turning humans into zombies. As he makes his way from Georgia to Gainesville, Florida and back, he picks up old and new friends and survivors. Flex reconnects with perhaps the strongest woman he's ever known, Gem Cardoza, his former girlfriend. Together they take his six-year-old niece Trina - the only uninfected survivor of his sister's famiy - and his infected sister Jamie, and make a run from central Florida back to his isolated Georgia home.

As they head north, they encounter another uninfected, Hemphill "Hemp" Chatsworth. Hemp is British and extremely smart. He holds a biology degree with a major in epidemiology, as well as a degree in mechanical engineering, both of which this group will need. Along with the crossbow-wielding Charlene "Charlie" Sanders and a pregnant Great Pyrenees dog, this small group uses street smarts and technology to defend against the new "Abnormals" that walk the earth. But Hemp is also compelled to learn how they got this way, and if possible, how to reverse the condition and save Flex's sister. So grab your machine gun and take a ride in their fortified vehicles and mobile lab; you're going to want these people on your side when the dead hunger....
