In this delightfully witty fantasy adventure, Dr. Greta Helsing, doctor to the undead, must defend London from both supernatural ailments and a bloodthirsty cult.

Greta Helsing inherited her family's highly specialized and highly peculiar medical practice. In her consulting rooms, Dr. Helsing treats the undead for a host of ills - vocal strain in banshees, arthritis in barrow-wights, and entropy in mummies. Although she barely makes ends meet, this is just the quiet, supernatural-adjacent life Greta's been groomed for since childhood.

Until a sect of murderous monks emerges, killing human and undead Londoners alike. As terror takes hold of the city, Greta must use her unusual skills to stop the cult if she hopes to save her practice, and her life.
