When a former police officer is murdered, Navajo Special Investigator Ella Clah will do anything to bring his killer to justice in Aimee and David Thurlo's Ghost Medicine

Former Navajo Police officer Harry Ute's body is found in an isolated part of the Navajo Reservation, rumored to be skinwalker country. This makes Navajo Police Special Investigator Ella Clah's job much harder--no one wants to speak to her for fear of incurring the wrath of the Navajo witches.

Harry's latest P.I. case involves tracking down property stolen from the county. This leads Ella to work with county Detective Dan Nez. Ella doesn't trust Nez but can't deny her growing attraction to him.

The murder and thefts turn out to be the tip of an iceberg. Previously unknown Navajo artifacts are being offered for sale, indicating a hidden dig somewhere on the Reservation. As danger mounts, Ella worries that her latest case might also become her last.
