She's trapped in a magical prison. To break out, she'll make a deal with the most dangerous prisoner of them all.

Sentenced for a crime she didn't commit, Samara is bullied by guards and tormented by the screams of her fellow prisoners. She's resigned herself to enduring her fifteen-year term... until she learns that the freedom she's been promised is the cruelest lie of all.

Now she's faced with a choice: resign herself to dying in the cold walls of Castle Greymere, or do the unthinkable and escape. But no one leaves Greymere alive. So to break out of the prison? She'll have to use one of the undead.

Raphael is the worst kind of monster: a vampire with a thirst for blood, the mortal enemy of witches, the same breed that killed her mother. And most importantly, he's unspeakably powerful, his supernatural strength tamed only by the enchanted cuffs forced on him.

He's her only chance at a life outside the prison walls.

The deal is simple: Samara unlocks his shackles, and he'll help her escape. But although Raphael agreed to help her leave Greymere, he never promised to let her go...
