They murdered her family. Then they sold her to the highest bidder.

Bought through the underground slave trade and whisked aboard a fortress-like container ship where wealthy loners wager on death matches, Sook Joo learns the rules fast: survive the cold, crowded cells, obey the crew, and always volunteer—or face a long swim home.

Below deck, girls vanish without explanation. Above deck, fortunes change hands on whispered odds. Violence is routine. Mercy is a liability. Every day at sea carries the promise that tomorrow might not come.

Sook Joo was raised differently. Her grandfather-sensei taught her discipline and composure over fear and subservience. He taught her that strength is quiet, patience is power, and survival favors the prepared. Those lessons become her armor in a place designed to break people.

The ship does not just carry orphans. It manufactures them.

Refusing to surrender to the fate chosen for her, Sook Joo begins to watch, learn, and prepare. Survival is only step one. Escape demands something far more dangerous.

There is only one way off the ship.
