The stakes have never been higher, for if Harper's taken by this new threat, Knox won't be able to stop his demon from taking a vicious pleasure in tearing the world apart. To survive Harper will need to embrace power that's darker than she's ever experienced and even Knox can't protect her from everything - though God knows nothing's going to stop him trying. It seems likely that someone is the third Horseman - but how do they know so much about Harper? It seems the impossible might be true - they have an enemy hiding at the very heart of the lair. It's a near miss and once a furious Knox has managed to pull his demon back into line there's only one thing clear - someone knows Harper's secrets and is systematically setting out to destroy her. Worse still, the attackers are trying to take her wings - the ones no one is meant to know she even has.

They're looking forward to some well-earned downtime - until Harper is attacked by mercenaries in the middle of her tattoo shop. Together, Harper and Knox have overcome just about every evil thing you can think of - from Horsemen of the Apocalypse to dark magic practitioners to Lucifer's insistent belief that he's hilarious. Knox and Harper's story continues as the Las Vegas lair - and its two infamous Co-Primes - face their most terrifying enemy yet.
