In the third book in the Charles Bloom Murder Mystery series...

For a thousand years, a hidden canyon on Rachael Yellowhorse's ancestral lands and the adjacent property owned by the Manygoats family has protected a masterpiece of petroglyphs deep inside the Navajo nation. These ancient works of art hold a secret with a power so strong their Anasazi makers kept them out of the reach of mere mortal human beings.

At his Santa Fe Indian Market show, gallery owner Charles Bloom unwittingly promotes the sacred rock-art images and sets in motion a cascading series of events that leads to the worst kind of human being searching out these hidden petroglyphs. Little could Bloom know that his discerning eye for art would connect him to a chain of murders stretching back 40 years earlier and to an individual who is not a collector of Native art but a psychopathic killer, the likes of which the Diné have no word to describe. Bloom will need all his observational skills to spot the killer before it's too late. It's a race against ancient history and for Bloom, time may finally run out.
