Ramage and the Saracens (Lord Ramage Series #17)

Ramage and the Calypso are sent to Sicily to track down Barbary Coast pirates—the Saraceni—who are capturing slaves and terrorizing fishing villages along the coast. Ramage is ordered to track the pirates to their home and destroy them before they can devastate another Sicilian town—and in the process, he and his crew must attempt to rescue hundreds of Italian prisoners!
