A sinking British ship, her crew and passengers-men and women alike-ruthlessly murdered at the hands of a French privateer. This is the nightmare Ramage and the crew of the Calypso stumble upon while engaged in a sweep for freebooters in the waters off Jamaica. Supported by his men in a thirst for righteous vengeance, Ramage sets sail to bring the murderers to justice.

The lieutenant is summoned by the Admiralty and given command of the brig, Triton. But like the rest of the Navy, Triton's crew has mutinied. Sympathizing with some of their complaints, Ramage also knows that if he fails to deliver three sealed dispatches to admirals off Brest and Cadiz, and in the Caribbean, he will become a convenient scapegoat.

The Calypso and her captain, Lord Nicholas Ramage, venture further into the French-dominated waters of the Mediterranean on an Admiralty mission to sink, burn, and destroy. Aiming to confuse and distract the enemy, Ramage and his men find themselves isolated and outnumbered as they take on the might of Napoleon's fleet.

The West Indian bases are desperate: post vessels-a vital communications link between England and the West Indies in the war against France-are mysteriously disappearing and no packets have arrived with orders in months. Were the privateers out in full force again? Had Napoleon's navy a secret new weapon? Lieutenant Lord Nicholas Ramage sets out from Jamaica to discover what treachery is threatening to throw the British navy into chaos.

Post Captain Ramage is prowling the Tuscan coast and far from English aid when he encounters a daunting French invasion fleet. As the enemy gathers strength, Ramage must decide how to thwart its actions with only the frigate Calypso and a pair of bomb ketches.

Ramage hopes to enjoy a well-deserved leave when he receives new orders: commission and take command of the Dido-a massive 74-gun ship, that carries enough weight of metal to destroy a frigate in a single broadside, or sweep a ship's decks clear of men. Accompanied by the courageous crew of the Calypso, Ramage ventures to sea once again-bound for the West Indies where he faces the challenge of commanding this massive weapon of war.

Barbary Coast pirates-the Saraceni-are capturing slaves and terrorizing fishing villages along the coast of Sicily. Ramage and his crew are sent to track them down before they can devastate another town.
