Private investigator Jake Helman has battled a demon, his minions, the walking dead, and beings from the dimensions of the Sphere of Light and the Dark Realm, but now he faces the greatest evil the world has ever known in the third installment of this loosely knit trilogy. Jake is hired by the wife of New York City mayor Myron Madigan to prove his infidelity. Meanwhile, the ex-girlfriend of his old partner Edgar needs Jake’s help when her son joins a cult that worships space aliens. And Jake’s late wife, Sheryl, now an “agent of Light,” asks him to locate a monster called the Destroyer of Souls—who may be responsible for the disappearance of the Biblical entity known as Abel. The investigation of Madigan leads to Karlin Reichard, a wealthy industrialist and political kingmaker—head of a cabal that has secretly manipulated world affairs for generations. In order to bring these men down, Jake must join them. With earthly and otherworldly forces marshaled against him, Jake battles human assassins and supernatural creatures in his quest to uncover the mystery behind the Order of Avademe and a monster willing to destroy heaven and hell to rule the earth.
