Daughter of Deception is the first book in the Family Lies series.  In a lot of ways, it is a paranormal Romeo and Juliet.  Duke is the regional head of the Network, an organization of people with special abilities dedicated to hunting demons.  Viola is the daughter of a man possessed by a powerful demon and from a family with a long, dark, and mysterious past.  Against his better judgment, Duke takes her back into the Network and walks right into the demon hunt of his life.
