Sniper Sergeant Marc Staille and his trusty rifle, Mat, are on bodyguard duty at a mining operation on a backwater planet. The resource-rich valley is crawling with tawnies, the native dirt-colored predators. Huge things that hunt in packs and kill as well with tooth and claw as Marc ever has with Mat. The rules change when a tawny uses an unexpected weapon: pheromones. Commander Hamm Orsonna, leader of the fefa clan, is determined to chase off the invading aliens. The one he sets out to capture for intel is scrawny and hairless, not very intimidating—until it takes out his entire squad. Seasoned warriors, felled from halfway down the valley by its metal death stick. Their sacrifice may be worth it, though. The alien male smells like he’s interested in making things right. He smells of other things too, but nobody else seems to notice. Before long, Hamm finds himself fighting off his own kind to defend the alien, who might be his people’s only hope for peace, and Hamm’s only chance for happiness.
