The adventurers now have their own island and port, but they’ll need more than one ship to defend it. They must scour the harbors and docks of the Shackles to recruit more ships and more crews to their flag. But when a rival from their past sends a fleet to attack them, they must defend their island home. And when they sail to his island to get their revenge, the adventurers discover a traitor whose betrayal threatens all of the islands of the Shackles.
