“This is a wonderfully important book which just may help the human race survive and thrive. In a clear and readable style, combining emerging science and sociological perspective as well as deep empathy and intelligence, Cain does a superb job of making us think. Readers will recognize behaviors at both ends of the introvert/extrovert personality spectrum as well as everything in between and will feel empowered to find their own comfort level for living.”
