There's a war coming to the City of Angels. In tunnels beneath the city, in the dark alleys among the homeless, demons lurk and Lucifer bides his time. One man knows. One man sees. One man walks those dark streets. Father Daniel Beckett's seen demons and he's spoken to the Devil, but he's never seen an angel and he's never spoken to God. He is God's warrior at war with God.
Heaven and Hell are closer than one might think as this arc draws to a close and Beckett and Duran come to terms with the changing world and new truths are revealed.
