There's a lot in life to be angry about, and we shouldn't be repressing that. The distinction between bad anger and good anger is a crucial one. A marvellous book which enhances our understanding of ourselves and others.

Irvine Welsh

Sam Parker's examination of anger is thrillingly incendiary… I haven't been able to think about anger in the same way since.

Alice Vincent, author of Rootbound and Why Women Grow

Compulsory reading … Grounded in wisdom from across time and culture, Parker offers us a variety of enlightening perspectives on this complicated subject. In today's maddening world dismissing anger simply isn't an option, we have to learn to live better with it.

Dr. Aaron Balick, psychotherapist and author of The Psychodynamics of Social Networking and The Little Book of Calm

Powerful and engaging ... Parker's fluent book, which draws on dozens of stimulating examples – from Aristotle to Tony Soprano – has wisdom to offer about tackling unhappiness ... Whatever your own background or temperament, there is much to digest and utilise in this moving story of recovery and renewal ... Good Anger is a potent defence of a vilified emotion – and a compelling invitation to sit with it a little longer.

Martin Chilton, The Independent

A delightful dive into our most maligned emotion. If you feel angry – and the whole world seems to be right now – this book will help you understand, and perhaps feel better about it.

Oliver Franklin-Wallis, author of Wasteland

This book is wise in the way a good therapist or a clever friend is wise – it leads us gently towards our greatest fears and reveals that the thing we're taught to suppress might be the key to making our lives infinitely better. Far from a book for angry people, it's a book for all of us who smugly shrug and say 'oh I never get angry'. It is quietly, gently revolutionary and it will make you feel both naked and relieved that you're not the only one struggling. Crucially, it will give you the confidence to turn anger to your advantage. It is one of those books you'll want to buy for the people closest to you to let them in on the secret. Because this book isn't just about anger, it is, above all, about hope.
