Zero Tolerance picks up a few weeks after the close of Maberry’s action-thriller Patient Zero. Dropping back into the world of former Baltimore cop Joe Ledger, the Department of Military Sciences, and flesh-eating zombies, fans of the series will finally see the tying up of a few loose ends.

This short thriller takes Joe Ledger into the mysterious, troubled town of Pine Deep, Pennsylvania, the setting for Maberry’s chilling Pine Deep Trilogy. In Pine Deep, nothing is what it seems.

When you have to kill the same terrorist twice in one week there’s either something wrong with your world or something wrong with your skills - and there’s nothing wrong with Joe Ledger’s skills. And that’s both a good and a bad thing. It’s good because he’s a Baltimore detective who has just been secretly recruited by the government to lead a new task force created to deal with the problems that Homeland Security can’t handle....

Before Baltimore cop Joe Ledger goes up against two competing groups of geneticists looking to continue the master-race program in The Dragon Factory, he must battle another foe using human test subjects for his sinister plans.

In this sweeping, threaded narrative of the global phenomenon known as the Vampire Wars, mankind is unwittingly infected by a millennia-old bacteria unknowingly exhumed by a scientific expedition in Antarctica. Now, in some rare cases, a person’s so-called junk DNA becomes activated. Depending on their racial and ethnic heritage, they begin to manifest one of the many diverse forms of the "others" that are the true basis for the legends of supernatural creatures. These aren’t your usual vampires and werewolves - it goes much deeper than that.
