Catherine Morland, a naive young woman with a penchant for Gothic novels, finds her expectations of high society challenged when she visits the titular estate. As she navigates the social intricacies of Bath and the mysterious atmosphere of Northanger Abbey, Catherine must distinguish between the dramatic tropes of her favorite fiction and the complex, often mundane realities of human behavior. Her objective is to secure her place in society and find love, but she is constantly thwarted by her own overactive imagination and the manipulative schemes of those around her. The narrative is presented through a third-person omniscient lens that frequently employs irony to critique the social mores of the early nineteenth century.

Northanger Abbey is widely regarded as a foundational work of literary satire that demonstrates the author's early mastery of irony. Readers often note how the novel functions as both a charming romance and a clever subversion of the sensationalist fiction popular during the period. The protagonist's growth from a sheltered girl to a more discerning individual provides a grounded center for the narrative's lighter, more comedic elements. Critics frequently highlight the work's enduring relevance in its exploration of how media consumption influences personal perception and social judgment. The text remains a staple of the canon for its wit and its precise observation of human folly.
