Portsmouth, 1782. His Britannic Majesty's frigate, Phalarope, is ordered to assist the hard-pressed squadrons in the Caribbean. Aboard is her new commander—Richard Bolitho. To all appearances the Phalarope is everything a young captain could wish for, but beneath the surface she is a deeply unhappy ship—her wardroom torn by petty greed and ambition, her deckhands suspected of cowardice under fire and driven to near-mutiny by senseless ill-treatment.
