When Detective John Stonebrook's friends hire a male stripper for his fortieth birthday party, his life takes a strange turn. For the stripper is Finn, a vibrant, headstrong Angel who has accidentally been bound as the Guardian Angel of a serial killer, possibly the same killer who murdered John's wife and daughter. As John battles his unexpected feelings for this young and beautiful male, and as Finn struggles to protect a man who may be a murderer, they are hounded by creatures of the dark, who seek to drag both Angel and detective down to the horror of the Beneath.
