After news of an approaching meteor, Shrader Marks and Cathy Pearson set events into motion that dramatically change the course of their lives. They lead a flotilla to the coast of Labrador seeking safety as the world is thrown into the chaos of volcanic winter.

Shrader Marks is having troubling dreams. When the scientific community acknowledges reports that the earth is in the path of an approaching meteor, he and Cathy Pearson set events into motion that dramatically change the course of their lives. As an anthropologist, Marks knows that Neolithic peoples lived on the edge of the Arctic Circle at the close of the last ice age. Pearson is a leader who engenders trust. Between the two of them, they manage to lead a flotilla of family sailors out the St. Lawrence Seaway to the coast of Labrador. As the world is thrown into the chaos of volcanic winter, this group finds its hope away from dependency on technology. Drawing on ancient ideas, the fleet follows the lead of Cathy and the intuition of Shrader, who is increasingly troubled by voices in the night.
