Is there a writer whose world you love to escape into? I don't just mean fantasy worlds, like Narnia or Hogworts or Middle Earth. I'm thinking of authors who wrote consistently about the same types of people living in the same area in the same time. Authors whose books create the illusion of a world. Thomas Hardy would be an obvious example. Most of his novels take place in 'Wessex'/rural south west England in the 1840s and 1850s. When you read him, it feels familiar. You know where you are. Dickens and Jane Austen are other obvious examples. Maybe the Brontes?
Personally, I love Oscar Wilde's world – you know, Oxford aesthetes smoking opium cigarettes and discussing art. Like Sherlock Holmes, it's a world of fog and gaslight and hackney carriages in muddy London streets. (I wouldn't have wanted to live in the real London of 1890 btw). P. G. Wodehouse is another writer who created a world I love.
