Book 7 of the series. Lord Ramage, the Navy’s youngest and most junior captain, is ordered to set sail for Diamond Rock, off the West Indian island of Martinique. It is a routine mission—to blockade the French in Fort Royal—but the 'Juno', his new command, is not a routine naval vessel. With a crew grown slack and mutinous under its alcoholic ex-captain, the 'Juno' is in no state to take on the French fleet. Surprised by an attack from ruthless French privateers, the new captain and his untried crew are stretched to within an inch of their lives.
