Black Tide Archive

After public disgrace and a nervous breakdown she barely remembers, marine archivist Mara Vale accepts a final chance at professional redemption: cataloging the contents of St. Brigid’s Reach, a decommissioned island research station scheduled for demolition off the Maine coast. The station was abandoned after every member of a private deep-sea expedition either vanished, died violently, or returned babbling about a choir beneath the water. Storm season has cut the island off from the mainland, but Mara tells herself isolation is exactly what she needs. Order. Silence. Work.

Inside the station’s sealed archive, she finds waterlogged journals, corrupted audio logs, impossible specimens, and repeated references to a trench that does not exist on any map. The deeper Mara digs, the more the station seems to remember its former occupants through her. Hallways shift, voices come through dead intercoms, and her own blackouts begin again—always ending with seawater in her lungs and salt beneath her fingernails. As the storms worsen and the surviving crew on the island turn on one another, Mara must decide whether she is uncovering a buried catastrophe or reenacting it. Because whatever was brought up from the trench is still alive, and it has started cataloging her back.
