23. The Walking, by Bentley Little (2000)
Just when you think you’ve read and seen every kind of zombie story, there’s a fresh spin on the living dead like Bentley Little’s The Walking that reignites your teetering passion for stumbling corpses. Instead of launching off with hordes of zombies, Little enters the Z-world through a single flesh-eating walker, lead character Miles Huerdeen's undead father. Using his background as a private investigator, Miles begins looking into the existence of more zombies in other families, tracing the origins of pulse-less troublemakers back to the Old West.
