Crackdown — Bernard Cornwell

Drug pirates stalk their victims in the treacherous waters of the Bahamas, then return to their fortress island of Murder Cay like primal sharks after a kill. Then comes skipper Nicholas Breakspear with the son and daughter of a U.S. senator. What should have been a simple de-tox cruise soon lurches into a voyage of terror and death when Breakspear is lured into a horrifying plot of cocaine, cash, and cold-blooded killings. Suddenly, he's racing through the shadowy kingdom of drug lords to save the woman he loves...one step ahead of his own murder, and one step away from the big crackdown on Murder Cay.
