Persuasion is indeed her best novel after Pride And Prejudice and take us on a journey of characters which we can relate to and connect with.
Anne Elliot, The Protagonist certainly is a lady with distinctive disposition and taste. She epitomizes benevolence and what a lady should be like... Her unbiased tendency to look at things without judging them and not affected by cursory and superficial luring manners worth praise.
I also liked Anne Elliot for maintaining a fine balance between her friend cum guardian and her love (Lady Russel and Fredrick Wentworth).
