My Demon Mate

The voice in my head tells me to commit murder.

All my life, I've only known pain, fear, and anger. I'm alone.
Except for the voice in my head. It tells me to act on some of my most diabolical thoughts. I can't listen, I can't carry out the acts, even if I've never wanted anything so much in my life.
When the voice manifests into a demon that says I've been promised to him for hundreds of years, I finally feel safe and cared for. Not only is he protective of me and my well being, he's hell bent on getting revenge against those that hurt me.
I'll tell him how.Contains mature themes.
