In the heart of the Caribbean, where fortified walls meet the glittering sea, Cartagena has long sheltered merchants, explorers, and pirates—and still guards secrets centuries old. When marine biologists Chris Dunn and Ray Salas uncover a shipwreck near Venezuela, their promising dive quickly spirals into clashes with smugglers, corrupt officials, and a long-buried pirate legacy.
As the team races to identify the wreck and protect their find, they become entangled in a dangerous struggle that spans Cartagena’s underworld as well as its academic circles. The search pushes them from open sea to museum vaults, each discovery bringing them closer to the ship’s true story—and to those willing to do anything to keep it hidden.
