For Richard Bolitho, the renewal of hostilities means a fresh command and the chance of action after long months of inactivity. However, his mission to support Lord Hood in the monarchist-inspired occupation of Toulon has gone awry. Bolitho and the crew of the Hyperion are trapped by the French near a dry Mediterranean island. After many hardships, full-scale battle commences.
