What's favorite book of all time and why?

My new favorite is Pride and Prejudice by Jane Austen. The main character of the book, Lizzy Bennet, is a smart young woman. She has to deal with issues of upbringing, morality, marriage and so on. At the end of the story she ends up marrying a guy that she used to hate. At first, she had a terrible impression of him. But during the story she discovered that he was an amazing guy and felt in love.
