Contemporary fantasy in the world of Strange Practice, starring Dr. Greta Helsing, whose family has been keeping the supernatural community not-alive and well for generations. When Greta Helsing, doctor to the undead, is unexpectedly called to Paris to present at a medical conference, she expects nothing more exciting than professional discourse on zombie reconstructive surgery and skin disease in bogeymen—and hopefully at least one uneventful night at the Opera. Unfortunately for Greta, Paris happens to be infested with a coven of vampires—and not the civilized kind. If she hopes to survive, Greta must navigate the darkest corners of the City of Lights, the maze of ancient catacombs and mine-tunnels underneath the streets, where there is more to find than simply dead men's bones.
