January 1782, Portsmouth. His Britannic Majesty’s frigate Phalarope is ordered to the assistance of 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 driven to near mutiny by senseless ill treatment.
