Of Saints and Shadows(1994)

Christopher Golden

A secret sect of the Catholic Church, armed with an ancient book of the undead called The Gospel of Shadows, has been slowly destroying vampires for centuries. Now the book has been stolen, and the sect races to retrieve it before their purpose is discovered: a final purge of all vampires. As the line between saints and shadows grows ominously faint, private eye Peter Octavian is drawn into the search. And he'll do anything to find the book ... for Peter Octavian is also a vampire.

Ostracized by his kindred for refusing to take part in the 'blood song', he cannot stand by and watch while they are destroyed. In a deadly game with a driven, sadistic assassin, the trail leads to Venice at the time of carnival, where the Defiant Ones, as the vampires are known, are engaged in a savage battle for their lives. Filled with plot twists, mystery, sex and violent death, Of Saints and Shadows is a spine-tingling thriller which opens the door to the world of Peter Octavian.
