This is a breath-taking treasure trove of a book. Robin and Joan share their lives' work in developing, practising and teaching the art of supervision. They describe in detail not only the models they have developed and the principles behind them but how they teach them - right down to the detailed design of their programmes, the exercises and experiments they use - and even the recipes for the cakes Joan bakes for the participants. But not only that. The book is a delightful read - it zings engagingly along, full of stories and vignettes, quotations and anecdotes. One feels privileged to meet the authors in all their humanity - their mistakes as well as their brilliance, their feelings and their experience. I feel deeply appreciative. - Professor Charlotte Sills, Ashridge Business School and Metanoia Institute, London. I shall return to the book regularly in order to savour each reflection and continue learning from the wisdom and humanity contained within it. - Els van Ooijen, psychotherapist, counsellor and supervisor in private practice in Bristol, a former visiting lecturer to the counselling and supervision courses at the University of South Wales, and author of Clinical Supervision Made Easy.
