Desert Heat - Turner P.H.

Navajo Witchery. Human Treachery.
Social worker Jordan Bia finds a child who escaped her captors and a life in the sex trade, but four other girls from her small Mexican village were not so lucky. Smugglers hide their human cargo in the hoodoos of a remote canyon on the reservation—a place the Navajo shun, fearful of the witches who practice their black rituals and feast on the dark energy of evil. Mysterious rites, omens of death, and bodies litter the canyon.
When she meets Navajo police officer Sam Tohee, sparks fly fueled by the danger of hunting men who buy and sell little girls. Techno savvy Jordan plots to trap the smugglers and free the rest of the children, but unless she and Sam can find the power to defeat the witches she may not live long enough to save the girls.
