Things get a little demonic in the latest Arcane Underwold novel from the author of Splintered. Thanks to their recent involvement with a magus crimelord and his demonic partner in mayhem, occult thieves Anna Ruiz and Karyn Ames are both stuck sharing head space with a demon. But while Karyn's possession has had the unexpected benefit of focusing her visions of the future, Anna's demon is spurring on her darkest urges, and it's only a matter of time before she acts on them—and hurts someone in the process. To save their skins, the two need to find a mysterious relic. But with their search taking them into some of the darkest places in the arcane underworld, Anna and Karyn will have to ally themselves with a group no self-respecting thief would be caught dead with—the Federal Bureau of Investigation...

Anna Ruiz is on a mission: Help her friend and partner-in-crime Karyn Ames break free of the tangle of hallucinations and premonitions that have cut her off from reality.

Between fighting Sobell’s battles with some seriously scary demonic forces and tangling with a group of violent fanatics who want to manipulate Karyn’s abilities for their own gains, Anna, Nail, and Genevieve are beginning to realize they’re in way over their heads. And now that Karyn’s secret about seeing the future is out, even more unpleasant parties—human and otherwise—are about to come knocking…
