In a world ruled by immortals, her only hope may lie in the heart of their darkest prince.

When my sister Belle goes missing, I venture deep into the cursed woods to find her. Ruthless vampires rule over our kingdom, and I'm terrified she's been murdered like so many others.

As I'm searching, I'm caught by the worst immortal of them all: Prince Cassius, dark Lord of the Bloodvale. I barely escape with my life, and the memory of his cruel beauty haunts me. So does the thought that Belle might be in his castle.

When I join the mortal resistance, I get the chance to infiltrate his stronghold. I'll find Belle and fight the vampires from within. It's not easy. I'm worked to the bone by a pair of wicked sisters and danger abounds, but the secrets I discover are worth it.

The castle is filled with magic…and so am I.

I'll have to keep my mission and power hidden if I want to survive, but the prince's stormy gaze follows me everywhere. When he chooses me as his personal servant, can I hide the truth? Or will the magnetic pull between us drag me to my doom?
