A faint rhythm rises from the ocean, too precise and deliberate to be natural.

When a research vessel investigates, the crew discovers something intelligent beneath the waves, something that watches, anticipates, and reacts. As the pulse spreads toward the shore, those who hear it find themselves drawn into a force older and more patient than humanity, one that may never let go.

A chilling story of oceanic horror, unseen intelligence, and the lingering threat that the sea may be listening to you too.
