A secret cargo. A dangerous rendezvous. And a mission that could cost Captain Rennie his ship, his honour — and his life.

War with Revolutionary France has begun, and Captain William Rennie is once again given command of HMS Expedient. Officially, he is sailing with a British expedition bound for the Caribbean. In reality, the Admiralty has another task for him: one hidden behind layers of secrecy and political intrigue.

At remote Ascension Island, Rennie must rendezvous with the French ship Marguerite, carrying a fortune supposedly intended for the Royalist cause. His orders are uncompromising: seize the cargo, scuttle the French vessel and return immediately to England.

But nothing about the mission is what it seems.

The treasure is not silver but gold. Loyalties begin to fracture, mistrust spreads through the ships, and when mutiny tears Expedient from Rennie’s command, he and Lieutenant James Hayter are forced into a desperate struggle to recover their ship and decide where their true duty lies.

Across storm-lashed seas, divided loyalties and deadly deception, Rennie must choose between obeying his orders and doing what he believes is right.

The Marvellous Sea is a sweeping Age of Sail adventure of mutiny, hidden treasure, secret orders and naval action, perfect for readers of Patrick O’Brian, C. S. Forester and Alexander Kent.
