Really interesting. I really enjoyed Ms. Cain's "case studies" and the explanations of the differences between "introverted" and "shy". It was refreshing to hear descriptions of introversion that didn't make us all come off as cold loners who are completely uninterested in people. I thought the book did a good job of looking at some possible causes of extroversion, the prevalence and attitudes toward introversion in various cultures, and some advantages to being introverted. At the same time, the book didn't come off as pro-introvert to the point of being anti-extrovert - thoughtful points were made about the advantages of each orientation, as well as practical advice on how to capitalize on their strengths. I especially enjoyed the sections that talked about how introverts and extroverts (especially married couples) can get along better.
A very entertaining and illuminating read (not since I read [b:Ten Things Every Child with Autism Wishes You Knew|163659|Ten Things Every Child with Autism Wishes You Knew|Ellen Notbohm|http://photo.goodreads.com/books/1328694413s/163659.jpg|157991] have I found myself nodding along with a book so much, thinking "that sounds like me" - only this time the correlation was even stronger).

If you are or know an introvert, you should read this.
