Gotta be Emma. I'm not as fond of the stick-in-the-mud Mr Knightly as some of the other heroes, but Emma is hands down my favourite of the heroines. She's passionate, loving, open-hearted, and is always, always screwing up. And there are so many wonderful supporting characters in the book, like Miss Bates, Mr Weston, Mrs Elton, Frank Churchill, and dear old Mr Woodhouse. I love them all.
