Promoted after the Battle of Camperdown, Kydd must pass the examination that will confirm him as a lieutenant. Technical competence is only part of the test: a former pressed man must also learn the manners and authority expected of a gentleman officer.
Service in HMS Tenacious takes Kydd and Renzi to Halifax and into contact with the young United States Navy during the Quasi-War with France. The voyage tests whether Kydd can command men who once stood beside him on the lower deck without denying the origins that made him a sailor.
