Former Pima County Deputy Sheriff Jake Blakely is now an Arizona Ranger, living by his own set of rules, Jake's Laws, dispensing swift gun-barrel justice to bad guys, as well as protecting the safe havens he's helping establish from the ever-present zombies. The safe havens are the seeds for the rebirth of a Staggers Plague-stricken nation. So far, it has cost him his girlfriend, Jessica, and his survivalist home in Split Rock Canyon. Now, zombies are pouring over the former U.S.-Mexico border by the thousands, driven north by remnants of the Mexican Army. Jake has a plan. It's bold and dangerous, and could easily cost him his life. That's never stopped him before.
