He can be anyone. Even you.

A dying inmate makes one last request: deliver a letter. Volunteer prison chaplain Thomas Reyes has broken the rules for the men inside before; what harm could one small act of mercy do?

By morning, the inmate is dead. So is an orderly. And a man walks out of the prison gates wearing a face that doesn't belong to him.

Marcus Blake is not who he says he is. He never is. A holy man. A killer. A miracle of flesh made clay, the result of an experiment that should never have happened, hunting the scientist who created him and burning through every life in his way.

Now Reyes's simple kindness has marked him. And when Blake turns toward the person the Preacher loves most, Reyes must find a man no one can recognize before Blake claims his final face.

From New York Times bestselling author J.D. Barker and I.O. Adler comes a relentless thriller about faith, identity, and the terrifying question: how do you hunt a man who can become anyone?
