Susan Horowitz Cain is an American writer and lecturer, and author of the 2012 non-fiction book Quiet: The Power of Introverts in a World That Can't Stop Talking, which argues that modern Western culture misunderstands and undervalues the traits and capabilities of introverted people. In 2015, Cain co-founded Quiet Revolution, a mission-based company with initiatives in the areas of children (parenting and education), lifestyle, and the workplace. Cain's 2016 follow-on book, Quiet Power: The Secret Strengths of Introverts, focused on introverted children and teens, the book also being directed to their educators and parents.
