The years 1892, 1595, 1923, and our modern day are connected by a time-travelling secret group called The Pentacle. Using sex magic, its members are tasked with thwarting vampire threats that stretch across time.
Rex Talbot, a Victorian playboy, and leader of the group, has found a grimoire in his collection, one sent forward through time with a warning: a vampire thought to be defeated is still at large, and has greater plans than feasting on the blood of innocent Londoners in Jack the Ripper fashion.
The Pentacle has been weakened, and their newly recruited member is as yet untried against the might of the vampire. Will sex magic be enough, or must they resort to more desperate measures?
