Jane Austen is one of my favourite authors and many are the times where I have lamented that fact that she didn't write more books. If it was up to me, she would have written ten times as many books! Alas, she didn't so for years I have been on the hunt for books that remind me of her style and where the characters have the same sense of humour, a similar innocence and spirit and the same capacity for reflection.
This is what I have found - if you like books by Jane Austen, you will also like:
