Antarctica, February 1931. Dr. Edie Kerr came south with her father's expedition to dig for fossils, and in the black shale they found creatures that should never have lived, then a door in the ice. Thirty hours ago her father went through it and has not come back. Now the men walk in their sleep toward the cliff, and at dawn Captain Briggs will blow the door shut. A polar horror story, where grief runs as deep as the ice.
