'This long-awaited book by Keith Tudor and Graeme Summers is a major contribution to transactional analysis (TA). The authors reprise their original model of co-creative TA and then go on to offer us a co-created dialogue that explores how their thinking and practice has developed - both individually and together - over the last fifteen years. They demonstrate in the book the very best of creativity in relationship. It is a must-read for anyone in the field of psychotherapy, counselling,or coaching.'- Professor Charlotte Sills, Metanoia Institute and Ashridge Business School'The traditional core concepts of transactional analysis established by Eric Berne and the other founding pioneers always felt unfinished. I could never formulate what was missing. Keith Tudor and Graeme Summers have filled the gap by describing the dynamic of co-creation. I consider this book deserving of being embraced as the current definitive text of transactional analysis theory and practice.'- Evan M. Sherrard, TSTA (Retired), International Transactional Analysis Association'The authors' co-creativity shines through in this fascinating book. The thinking throughout is humanistic, grounded, challenging, and positive. The combination of willed self, shared responsibility, and limited conscious control creates the conundrums of therapeutic, coaching and other demanding relationships that require just this kind of intelligent and clear attention.'- Professor Nigel Nicholson, London Business School, author of The 'I' of Leadership'Built solidly on the background and context of co-creative transactional analysis, the theory is fleshed out step by step and given life and colour through the description of the methodology. The inclusion of contributions from other transactional analysis theorists gives this volume added depth, diversity, and value.'- Charlotte Daellenbach, TSTA(P), International Transactional Analysis Association'Professionals involved in helping others heal, change, and grow will find sophisticated guidance and provocative questions to take their work forward. They will also find a vivid illustration of the kind of ongoing dialogues that both free up and ground the individuality and insight of all involved.'- Gianpiero Petriglieri, Associate Professor of Organisational Behaviour, INSEAD'These experienced practitioners thoughtfully grasp and constructively transcend limitations in their initial training while retaining the value of its core approach.'- Professor Herbert Hahn, Member the International Association for Relational Psychoanalysis and Psychotherapy, the International Society for the Psychoanalytic Study of Organizations, and the International Organisation of Group Analytic Psychotherapy
