Hey there. I heard your favorite book is Pride & Prejudice. The original title of the book was supposed to be "First Impressions".
Yes! I'm glad Austen changed the title, though. Pride & Prejudice is more appropriate for the contents of the book.
One of Austen's favorite novel is Fanny Burney's Cecilla. She actually got the title Pride & Prejudice from Cecilla as the phrase was used three times in the book. 
I read Cecilia once just because I knew Austen enjoyed it.
Austen finished the novel in 1797 but it took 16 years for it to get published. When it did get published, Austen had to do it anonymously as professional female writers were controversial.
