The epic conclusion of The Jake Helman Files! For two years, private investigator Jake Helman has battled powerful supernatural forces at great physical and emotional cost to himself. He's stopped a serial killer who collected the souls of his victims, destroyed a mutant octopus god, battled zonbies on a Caribbean island, and stood toe to toe with angels and demons. If Jake has learned one thing, it's that he can't run from his past. New York City lies in ruins in the wake of Jake's battle with Lilith, the storm demon. Jake wants nothing more than to lead a normal life with NYPD detective Maria Vasquez, but that is not yet possible: one of his closest allies has betrayed him, and he must locate her before she uses his secret files to unleash unholy hell on earth. In his most pulse-pounding life-or-death adventure yet, Jake tackles adversaries who have aligned to destroy him. He must solve a mystery, destroy a hive of monsters, and confront the most diabolical minds he has ever encountered--to save his own soul.

In this action-packed novel, Jake Helman—the ex-cop and zombie killer—has set up shop as a private investigator in lower Manhattan.
