My favorite part of the book is when Jane first stands up to Mr. Rochester. It is really Victorian flirting, and it is hilarious! She does not fit his definiton of a governess or a female, and he does not fit her definition of a wealthy man.
The most intriguing part was how St. John was manipulating Jane into marrying him. I couldn't believe that he almost had her eating out of his hand when he told her what to do and when he convinced her to learn that Indian language with him. I was amazed that a "man of God," (like he claimed) would be so selfish and treat Jane with such disrespect. Luckily, she was able to break free from his crazy plan to move to India and be a missionary.
