"Persuasion" is Jane Austen's last completed novel. She began it soon after she had finished Emma, completing it in August, 1816. She died, aged 41, in 1817; "Persuasion" was published in December of that year (but dated 1818).
"Persuasion" is connected with "Northanger Abbey" not only by the fact that the two books were originally bound up in one volume and published together two years later, but also because both stories are set partly in Bath, a fashionable health resort with which Jane Austen was well acquainted, having lived there from 1801 to 1805.
