A vicious supernatural entity, conjured by the most profane and forbidden magic, is prowling the darkened alleys and backstreets of New Orleans. The only evidence of its existence is the trail of charred corpses it leaves in its wake. When the evil strikes too close to home, lab courier Jake Presnall learns first-hand that dark forces are plotting to renew their ancient struggle against an unsuspecting world. And when a recently unearthed religious artifact finds its way into his possession, a silver chain with a long history and strange powers of its own, Jake will land at the epicenter of a war that has been brewing since the beginning of time itself.
