Lady Susan
This is a very strange book. Unlike other Austen novels, the main character is really quite a terrible person. The ending is appropriate, but comes unconvincingly quickly. In addition, the epistolary form makes it a little difficult to follow. Lady Susan is definitely not as good as Austen's other works, but I suspect Austen knew that. Although she wrote the book earlier in her life, she never attempted to have it published.
