The hunters have become the hunted.

Sergeant Dominique Davis has spent her career hunting killers. She knows how monsters think. She knows how they hide.

She never expected to become one.

After surviving an attack that should have killed her, Dominique awakens with impossible instincts, impossible strength... and a hunger she cannot explain. As bodies begin to pile up and her own memories become increasingly unreliable, the line between predator and protector begins to disappear.

Branded a murderer by the city she once swore to protect, Dominique is forced underground, where an ancient world of vampires, blood rituals, and forgotten wars has existed in secret for centuries. Every answer uncovers something worse. Every ally carries an agenda. And somewhere in the darkness, a grieving hunter has decided that humanity can only be saved through extinction.

The deeper Dominique falls into that hidden world, the more one terrifying question refuses to leave her.

What if the monsters were never the greatest threat?

Because something far older is waking.

And it is hungry.
