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.

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.

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, finally reunited with his beloved Sarah, hopes to spend at least a few quiet weeks with her. Instead, he is summoned by Admiral Nelson himself. His orders: Ramage is to join Nelson's fleet blockading the combined French and Spanish navies in the port of Cadiz. But Nelson's plan is not merely to blockade the enemy's fleet. He intends to confront it head-on in the biggest naval battle the world has ever seen.

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 youngest captain in His Majesty's Navy, with a reputation for landing impossible assignments, Lord Ramage is dispatched to the Caribbean islands of Martinique and Diamond Rock. The mission seems humdrum: barricade the French within Fort Royal. But sent to sea in the Juno with a crew grown restless and undisciplined under the prior command of a drunk, Ramage realizes his vessel may not be up to battle with the French.

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.

Admiralty spies are hunting for British officers and allies trapped on the mainland, among them Ramage's first love, Gianna, the Marchesa di Volterra. Ramage returns to the Tuscan coast, where Bonaparte holds a group of hostages for an unknown fate.
