A thrilling new Victorian-era urban fantasy for fans of Kevin Hearne’s Iron Druid Chronicles, the Showtime series Penny Dreadful, and the Sherlock Holmes movies featuring Robert Downey, Jr.
 
With a flood of dark magic about to engulf Victorian London, can a handful of heroes vanquish a legion of the undead?
 
When monster-hunter Malcolm MacFarlane comes across the gruesome aftermath of a ritual murder in a London church, he enlists the help of magician-scribe Simon Archer and alchemist extraordinaire Kate Anstruther. Studying the macabre scene, they struggle to understand obscure clues in the ancient Egyptian hieroglyphics carved into the victim’s heart—as well as bizarre mystical allusions to the romantic poetry of William Blake. One thing is clear: Some very potent black magic is at work.
 
But this human sacrifice is only the first in a series of ritualized slayings. Desperate to save lives while there is still time, Simon, Kate, and Malcolm—along with gadget geek Penny Carter and Charlotte, an adolescent werewolf—track down a necromancer who is reanimating the deceased. As the team battles an unrelenting army of undead, a powerful Egyptian mummy, and serpentine demons, the necromancer proves an elusive quarry. And when the true purpose of the ritual is revealed, the gifted allies must confront a destructive force that is positively apocalyptic.
