Jon Shaw is a thorn in demons’ and state exorcists’ sides alike. He answers to no one but himself and roams the streets of Los Angeles at night, looking for answers. He’s the one demonic traders have on call to resolve a botched ritual and to deal with a possessed on a rampage—the only exorcist most would trust to do a tough job. But as the years pass, he’s no closer to locating the gate of Hell. Until he finds help from an unexpected ally: a hybrid incubus named Azeroth, forced to toil in an underground brothel in the Deep Market of Los Angeles. Azeroth is a dangerous creature to associate with, but sometimes it’s better to deal with the devil you know than the devil you don’t.
