Pirate Latitudes | Michael Crichton

The target is Matanceros, guarded by the bloodthirsty Cazalla, and considered impregnable with its gun emplacements and sheer cliffs. Hunter's crew of buccaneers must battle not only the Spanish fleet but other deadly perils - raging hurricanes, cannibal tribes, even sea monsters. But if his ragtag crew succeeds, they will make not only history ... but a fortune in gold.
