Consume Me by Heather Hildenbrand

The Whispering Daggers once saved me from certain death.

Ever since, their dark magic has been my prison. They whisper vile orders inside my head. Commanding my hands for their own uses. Demanding blood spilled and life ended all so they can feed.
The only way to sever their hold over me… is to die.
Then they make me an offer I can’t refuse—one more kill, and I’ll be free.
I accept.
On All Hallows Eve, I come face to face with my target.
Noctan. Tall, lethal, breathtaking. A warrior with shadows in his eyes and power in every step. A predator in his own right, he should have meant nothing more to me than freedom gained. Just another mark.
But fate has other plans. This beast in a man’s body is my mate.
Now the daggers want his life, and my body burns for his touch.

I can’t kill him. I can’t stay away from him. And the closer we get, the more I realize he’s just as dangerous as the magic that owns me.
The daggers want to corrupt me. Noctan wants to claim me.
Either way… I’ll be consumed.
