Northanger Abbey by Jane Austen.Read about another entry on the list.
Jane Austen’s only Gothic novel, and allegedly the first novel she finished (1798-99), which means that, impressively, she wrote it in her early twenties. Northanger Abbey wasn’t to be published in her lifetime, but only after the success of her other books. It’s great fun because of the meta aspect: the main character reads The Mysteries of Udolpho and begins to see Gothic intrigue everywhere.
