Sails on the Horizon — Jay Worrall

The year is 1797. Napoleon Bonaparte is racking up impressive wins in the field against the enemies of revolutionary France, while on the seas England is putting up a staunch resistance. Twenty-five-year-old Charles Edgemont is second lieutenant aboard the British ship Argonaut. When orders come for the Argonaut to engage in an all-but-suicidal maneuver to prevent the escape of Spanish ships off the coast of Portugal, he leads his gun crews bravely -- until the deaths of the captain and first lieutenant elevate him to commander.
For refusing to yield to enemy fire, Charles is permanently promoted and generously rewarded by the Admiralty, becoming wealthy beyond his wildest dreams. Yet upon his return home, his newfound riches prove no help when it comes to winning the heart of Penelope Brown, who regards war as sinful and soldiers as little better than murderers. Changing Penelope's mind may just be the hardest battle Charles has ever fought -- at least until fresh orders send him back to sea, where he faces a formidable adversary in a series of stirring battles of will and might.
