The Valiant Sailors (Volume 1) (The Phillip Hazard Novels, 1)

Sailing beneath the ominous cloud of war between Turkey and Russia, the frigate Trojan is on her way to the Black Sea, carrying on board a mysterious passenger, a young woman whose identity must be concealed by orders of the Admiralty. Although First Lieutenant Phillip Hazard is captivated by the charming young woman, he has a far more pressing concern: the Trojan's captain is a sadistic despot-and quite possibly insane.
