A corpse discovered in Whiskey, Arizona points to the work of an emerging drug cartel south of the border. When stolen artifacts from Whiskey's museum lead to more bodies - several of them brutally mangled - Chief of Police Rye Dawlsen fears there is more to the mysterious murders than drugs, corruption, and the Mexican Mafia. The son of a gringo father and a Navajo mother, Dawlsen knows the legend of the Navajo Skinwalkers ... werewolves ... but refuses to believe such creatures exists. Rumored to travel in animal form, Skinwalkers attain the highest level of pure evil when they kill a close blood relative. Dawlsen might discount such rumors except the killings seem too vicious, even for the violent members of "El Aguila," The Eagle.
Something evil lurks behind the cactus and sagebrush of Arizona's desert. An evil so vile it threatens to destroy the people of Whiskey and Dawlsen's feeble faith in the goodness of God."
