Emma

From Wikipedia: 

Emma is a novel written by English author Jane Austen. It is set in the fictional country village of Highbury and the surrounding estates of Hartfield, Randalls and Donwell Abbey, and involves the relationships among people from a small number of families. The novel was first published in December 1815, although the title page is dated 1816. As in her other novels, Austen explores the concerns and difficulties of genteel women living in Georgian–Regency England. Emma is a comedy of manners.

Before she began the novel, Austen wrote, "I am going to take a heroine whom no one but myself will much like." In the first sentence, she introduces the title character as "Emma Woodhouse, handsome, clever, and rich, with a comfortable home and a happy disposition... had lived nearly twenty-one years in the world with very little to distress or vex her." Emma is spoiled, headstrong, and self-satisfied; she greatly overestimates her own matchmaking abilities; she is blind to the dangers of meddling in other people's lives; and her imagination and perceptions often lead her astray.

Emma, written after Austen's move to Chawton, was her last novel to be published during her lifetime, while Persuasion, the last complete novel Austen wrote, was published posthumously.

The novel has been adapted for a number of films, television programmes and stage plays.
