The Quetico-Superior Wilderness: more than two million acres of forest, white-water rapids, and uncharted islands on the Canadian/American border. Somewhere in the heart of this unforgiving territory, a young woman named Shiloh -- a country-western singer at the height of her fame -- has disappeared. Her father arrives in Aurora, Minnesota, to hire Cork O'Connor to find his daughter, and Cork joins a search party that includes an ex-con, two FBI agents, and a ten-year-old boy. Others are on her trail as well -- men hired not just to find her, but to kill her.

As the expedition ventures deeper into the wilderness, strangers descend on Aurora, threatening to spill blood on the town's snowy streets. Meanwhile, out on the Boundary Waters, winter falls hard. Cork's team of searchers loses contact with civilization, and like the brutal winds of a Minnesota blizzard, death -- violent and sudden -- stalks them.
