Junior Fish and Wildlife project manager Becca Olsen is desperate to save her wolves, her relationship, and her job in the desolate New Mexico desert, but something is horribly wrong in the Land of Enchantment. When the perky voice of the dimpled desk jockey fails to assure ranchers their cattle are safe, her first wolf reintroduction campaign is in danger of crumbling like dry stalagmites in the nearby caverns. Mutilated cattle are found in the desert. Wolf tracking collars disappear. Are angry ranchers killing her babies, or is there some truth to the legend Fantasma del Gris, Ghost of the Gray?
