Commander Darius Vane was the youngest captain in the U.S. Navy until a betrayal cost him his command, his crew, and his honor. Disgraced and exiled to a forgotten island in the Strait of Hormuz, he discovers an ancient throne buried beneath the Persian Gulf—a throne that responds only to the blood of kings. When Iran blockades the strait and the world spirals toward war, Darius awakens a power older than empires. With a kingdom of sea-folk at his command, a sentient warship forged from living iron, and a mysterious AI intelligence that speaks through the ocean itself, he must choose: reclaim his mortal life or embrace a destiny that could reshape the world map. The Strait of Hormuz was always the most dangerous chokepoint on Earth. Now it has a king.
