As lovely and intriguing as the title is, the book itself just seems to be summaries of the plots of Sense and Sensibility, Pride and Prejudice and Mansfield Park, with some commentary interjected about how some of the phrases used by the female characters were sharp, spiteful, sarcastic, etc.
If you are reading the books themselves, i.e. instead of this one, you'd be able to spot for yourself if a character was being sharp, spiteful, sarcastic, etc. I don't generally need a study guide to point out the author's intent. If the author doesn't manage to do this in the original book, I tend to be of the opinion that either the author has failed me, or I have failed the author. So, as far as my estimation of this particular book goes...Meh.
