A narrow strait. A stalled ship. Two rival powers watching.

Captain Mara Solis is guiding a container ship through one of the world's most strategically sensitive waterways when the engine dies without warning. The vessel begins drifting across disputed waters in a corridor already crowded with warships, intelligence operators, and political suspicion.

On shore, maritime controllers race to prevent a disaster that could close the strait to global trade.

In the engine room, engineers fight a software-driven failure that threatens to leave the ship powerless in the current.

And across the water, rival naval officers watch the drifting vessel as an opportunity neither side can afford to mishandle.

What begins as a mechanical fault rapidly becomes something far more dangerous: a test of nerve between nations where every move is visible, every decision is political, and a single mistake could turn a maritime accident into an international crisis.

Black Current is a tightly wound geopolitical thriller about modern shipping, maritime infrastructure, and the fragile balance that keeps the world's trade routes open.
