In Jane Austen lines these books are excellent. I loved them all and I've read all his works also (Pride and Prejudice, Emma, Persuasion ...) Lady Susan is surprising. The history established through the exchange of correspondence and the final of the book is in such truculent style is very thought of taking.
The book of Elizabeth Gaskell's great and portrays human nature and the status of women in England. A must read if you also love Jane Austen but in a different style.
