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.
A peaceful small town is ripped asunder as its children go missing and many are found wandering disoriented or dead. Someone – or something – is hunting them down one by one. Coming to a place where trust in anyone is non-existent and faith in a solution is fading fast, Beckett and Duran must team up with one victim’s brother to track down the monster hunting the children.
