It is September 1804. England stands alone against France and the fleets of Spain, anticipating invasion. Vice-admiral Richard Bolitho has his own troubles to settle at home too. But his time on land is broken by an urgent summons from the King. Once more Bolitho hoists his flag above the veteran seventy-four-gun ship Hyperion and sets sail - this time with a new squadron headed for the Caribbean. Ordered to plan and effect a daring raid on the Spanish Main, Bolitho spares himself nothing, from here to Antigua, where he rediscovers a passion which defies every convention and threatens his reputation. And the future of the Hyperion is at risk too. Set to clear the path to victory there is a constant fear that this may be her final battle.
