What do you do when the monster you fear most lives inside your mind?

I thought I knew survival.

As a scavenger picking through the battlefields in the middle of the endless war between demons and the angelic ephilium, I'd spent my life dodging death, staying invisible, and keeping my sister safe.

Then I took her place on an altar.

My blood was meant to unleash an ancient evil.
>Instead, Syrus, the Demon Lord of Malice, claimed me as his host.

Now I can't breathe without him in my mind-commanding me, taunting me, tempting me.

Worse, I know his power will eventually consume me, burning through my veins and tearing me apart from the inside out.

I can't escape a monster when he lives beneath my skin. But the Lord of Malice offers a bargain:

Help him uncover who is sabotaging souls before they reach his domain, and he will release me.

Except somewhere between hunting traitors in his realm and unraveling secrets in mine, the demon who should be my captor becomes my protector.

And all too soon his hold on me is the drug I fear I can't survive.

Because when I finally learn the truth, I may find something I want even more than my freedom.

Perfect for fans of the Nightmare in One Dark Window and dark Hades and Persephone romances, this demon-possession romantasy delivers a shadowy MMC, obsessive tension, and the ultimate forced proximity.
