Detective Wolf Regnum has been living two lives, one as a father and Police Detective for the Richmond Police Department, the other as a member of the Vigiles, an ancient organization with one purpose, to watch the night. But when a scream shatters the darkness, both his worlds collides and everyone he loves may well pay the price.

A girl speaking a language he cannot understand is lost in the city, but someone is looking for her. That’s when Wolf must accept that vampires and wolves are not the only monsters in the dark…there are humans as well, and when they invade his home to find her, threatening his son and the family he is desperately trying to build, Wolf must decide how far he is willing to go.
