Dreadful Company (A Dr. Greta Helsing Novel Book 2);

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.
