Sailing on the Mediterranea Sea in the late 16th century, the crew of the corsair ship Blackfeather travels from port to port, attacking merchant ships for wealth and glory. Under the leadership of the Arabic Captain Hasan al-Maghrebi, the cultural melting pot of crew struggle to survive in the harsh world of criminals, business politics, and legal authorities. The quartermaster of the ship, monk-turned-pirate Dominico Sciocco, helps guide the ship through a whirlwind of kidnapping, deception, and warfare, to fix problems from the lives of his crewmates. The Blackfeather crew aren't just sailors, they're family. And no treasure is more valuable than family.
