After a gruesome betrayal, vampire Sebastien Vilmont is flung into a whirlwind cat and mouse game when his traveling party is ambushed by an opposing group of bloodthirsty vampires. Maurice, the leader of Sebastien's coven, makes the decision to not only wage war against the opposing vampire clan, but a clerical organization known as The Diocese Club who wishes to exterminate all vampire-kind. Trying desperately to protect the secrecy of their coven's location below the streets of Whitechapel, London, Sebastien finds himself at odds with Maurice in his desire to not engage in all-out war with the renegade Catholic faction. At the same time, he must also battle the other vampire coven to guard their anonymity from humans. In doing so, Sebastien is forced into choices and alliances he might not otherwise have made. Set in the tone of Victorian England, The Coven is a thrilling and horrific journey through the seedier workings of the vampire underworld, and pious ideology of The Diocese Club.
