In 1973, Owen Vance was rescued from a drifting cargo ship in the middle of the Pacific. He was the only man left alive. At the official inquiry, Owen told them what they needed to the engine failed, the crew succumbed to thirst and despair, and a storm swept eleven men into the sea. For thirty-eight years, he has lived with the truth. The MV Nicobar left the coast of Peru carrying thirty-one people across an ocean that had gone strangely empty. No birds. No dolphins. No fish beneath the surface. Then the engine died. Soon, patches of the ship's steel turned impossibly cold. A sailor vanished from an empty deck. The echo sounder began detecting something enormous directly beneath the hull. Something that had risen from miles below. As the stranded crew seals itself inside the ship, men continue to disappear. Then voices begin calling from the water—voices belonging to people Owen knows are already dead. And whatever is beneath the Nicobar is getting better at speaking. MARINE SNOW is a claustrophobic deep-sea horror novella about isolation, starvation, an ocean stripped of life, and something ancient below the reach of sunlight that has finally come looking for food.
