Beautiful, bold Lt. Ligachev is two months into her first command position at a pumping station in the Siberian oil fields when her men are slaughtered by an invisible foe. She escapes, barely. New York City detective Schaefer has run into Predators before on the mean streets of the United States, and survived. Now Ligachev and Schaefer are sent to winter-ravaged Siberia by their bickering governments to eliminate the Predators -- if they can just keep the Americans and Russians from killing each other first.
