Portland homicide detective Jeremy Hafland has seen everything the city's shadows can throw at him. But nothing in twenty years on the force prepared him for the night an ancient entity chose him as its host.
The Jindall doesn't ask permission. It moves through Jeremy like a second heartbeat - older than language, hungry for violence - and suddenly the dead don't stay quiet around him anymore.
Now Jeremy is caught between two wars he didn't start. On one side: werewolves with a code and a grudge. On the other: the Manes - lab-engineered super-soldiers funded by a government that doesn't officially exist, commanded by a man known only as Dr. Demise. The scientist isn't interested in peace. He's interested in what's living inside Jeremy.
The badge used to mean something. Now it's just metal.
How long can a man hold the line when the monster keeping him alive is the most dangerous thing in the room?
