Which Austen novel features Captain Wentworth?

The Austen novel featuring Captain Wentworth is 'Persuasion.' Captain Frederick Wentworth is the novel's principal male character and the former fiancé of Anne Elliot, its protagonist.

Eight years before the story begins, Wentworth and Anne fell in love and became engaged. Anne ended the engagement after her family friend Lady Russell persuaded her that Wentworth's uncertain fortune, lack of aristocratic connections, and dangerous naval career made him an unsuitable match. The separation leaves both characters with lasting regret.

Wentworth later returns from the Napoleonic Wars as a successful Royal Navy officer. His wealth and professional achievement have changed his social position, but Anne's feelings for him remain. Their renewed meetings expose the consequences of pride, wounded feelings, and outside influence. The novel's title refers to the powerful effect that persuasion has on personal decisions, especially Anne's earlier choice to give him up. Wentworth's famous letter eventually allows the couple to reconcile.
