The Supernatural Order guides and trains any vampire hunter who manifests the gifts of a seer, but Flynn is far from a typical recruit. His bloodstained reputation leads their High Council to hand him a death sentence, not wanting to gamble on the supposed rehabilitation of a vampire assassin. His watcher, Monica, refuses to leave him to his fate, and they must avoid capture while deciphering a riddle left by Lydia Davies. The mission takes them from Philadelphia to the Windy City of Chicago, with a master seer named Julian nipping at their heels.
As Peter emerges from the crimson shroud of his alter ego, he can't deny that the Order's fears are well founded - he's still a vampire, with a vampire's needs. Finding common ground between his dual natures seems impossible, except in one forbidden thing. Monica draws out his almost forgotten humanity, while tempting the immortal who remembers the intoxication of fresh blood cascading down his throat.
With one foot still in the dark and one in the light, Peter must keep his fangs hidden and his past a secret. Their few human allies can't be trusted with the truth. Their immortal enemies would either kill him or use him as a pawn in a war he has no intention of fighting. Even the woman who believes in him has an agenda, to show him what it means to be a savior rather than a devil. Only one thing truly remains certain. Seer or assassin, good intentions or dark desires, his hands wield a sword with the precision of a capable killer. And when his deceptions unravel, those skills will be the only thing keeping him alive.
