<p>This book describes a series of ground-breaking residential workshops in therapeutic counselling in the 1960s, for people working in mental health and social care disciplines seeking to expand and deepen their reach. The work is unique in the scope of its research into the process and outcomes of such active immersive enquiry in this area. Besides a wealth of more systematic features, the author invites us into the initial conversations in the meeting room, and then follows the group members back into their lives, allowing us to see both early outcomes and the impact of participation up to ten years later. Finally, Barrett-Lennard reflects on the extended history of the intensive workshops and the related group work in other contexts they led into. He makes a compelling argument that such an intensive participatory process is as powerful today as it was in the 1960s. The blend of rich qualitative and empirical data and theory is a unique strength. It will be a great resource for students and scholars in applied psychology and psychotherapy, as well as for practicing therapists and trainees committed to meaningful work with their client groups.<br/></p>
