THE ICE KEPT IT SECRET FOR A THOUSAND YEARS. NOW, THE ICE IS KEEPING THEM IN. On Norway's Jostedalsbreen glacier, an energy signature that shouldn't exist has started pulsing beneath the ice. Captain Kate Vance is sent in to secure the dig, where Dr. Martin Calder swears he's found a Viking longship, impossibly intact after ten centuries. But Vikings didn't build ships with a power source. A reckless act triggers an ancient beacon. A catastrophic storm slams into the mountain, killing every signal and sealing the base behind a wall of ice and snow at sixty below. But the storm is just the cage. The real threat is already inside. They call them Hunters — armored cyborgs that move through the crawlspaces between the walls, mimicking the voices of the dying to draw the living out. They aren't hunting for sport. They're harvesting. And Vance is starting to work out the terrifying truth of what that makes Earth. With her people dead or dying, her ammunition running out and no way off the mountain, Vance is left with one impossible choice. To save what's left of her team, she has to go deep into an alien ship buried in the ice. There is only one weapon that can kill them. It whispers in her mind. It doesn't use ammunition — it uses her. And the only question is how much of herself she has left to spend. And deep under the glacier, the engines are warming up. The translation on the longship's hull was never a name. It was a warning: When the sky turns white, the Hunt begins. Fallow is the explosive first book in a new military science fiction series. Fans of The Thing, Aliens, and the Frontlines series will find themselves right at home in the ice.
