This book will be on the shelves in Jan. 2012. I'm reading an advanced reading copy from the publisher and I think, as a confirmed introvert, that I'm really going to like it.
I've finished the book and I must say that it gave me some really good insight into our "extrovert ideal" culture and the pressures that are brought to bear upon those who don't fit that mold. Especially fascinating is research done on infants that shows introversion/extroversion characteristics at very early ages. This book encourages introverts to accept their temperaments, to appreciate the positive aspects of being "quiet", and gently advises us how to feel more comfortable in a world that does not always value introspection. Good advice for parents as well on raising introverted children.
