A book that has already inspired thousands of readers is now published in paperback. Cain shows how the brain chemistry of introverts differs from that of extroverts, and how society misunderstands and undervalues them. She then provides introverts with the tools to better understand themselves and take full advantage of their strengths. 'I can't get "Quiet" out of my head. It is an important book - so persuasive and timely and heartfelt it should inevitably effect change in schools and offices' Jon Ronson, "Guardian"
