For centuries, a mysterious order of priests jealously guarded the secret of the Bond of Saint Marcel: an occult ritual that enabled priests of the Order to enslave vampires and use them as unwilling soldiers against their own kind. When 16-year-old Kat Johnstone inherits an ancient family signet ring she is swept into a world of fatal secrets and a centuries-old quest for vengeance. But with the ring, Kat has also inherited the power to command a vampire, and he may be her only hope of survival. Art by five-time Eisner nominee Christian Gossett (Red Star).
