Jane Austen is J.K. Rowling's favorite author of all time, and "Emma" is her favorite of her books. "I've read all her books so many times I've lost count," she told Amazon. Of those many book-reading sessions, she said she read "Emma" at least 20 times.On Oprah's website, Rowling cited Virginia Woolf to describe Austen's mastery of the novel: "For a great writer, she was the most difficult to catch in the act of greatness."
