Geophysicist Alex Cave receives and urgent message about unusual seismic activity in the Pacific Northwest. The Mount Baker Volcano is showing signs of an emanate eruption. He leaves to investigate and discovers the increased activity is also causing the Polar Ice Sheet to expand by thousands of square miles in a matter of minutes. If he can't find a way to stop it, the planet will enter a new ice age.
Alex and his friends begin a desperate race to the Arctic Ocean, barely escaping capture by pirates along the way. When they reach an unknown island in the Bering Sea, they discover the source of the sudden freezing temperatures and seismic activity. A piece of advanced alien technology.
