In the Arctic Ocean, the US Coast Guard icebreaker Terra Nova batters its way through the pack ice. There shouldn't be anyone near them for hundreds of miles. But then a lone skier, half-dead with cold, emerges out of the snow. His name is Tom Anderson, and he is the only survivor of a disaster at Zodiac Station, a scientific research base deep in the Arctic Circle. He tells an incredible story of scientists and spies, of lust and greed, of jealousy, mayhem and murder. But his tale simply doesn't add up.
