This book is an excellent introduction to the developing field of supervision for coaches and mentors. The wide ranging contributions sit well together and despite one or two minor inconsistencies, parallels can be drawn between different chapters, allowing bigger themes to be identified. I really liked the inclusion in most chapters of further reading, questions and development activities to stimulate reflection and evaluations of the subjects under discussion, including in many cases, the pitfalls. Although it contains a lot of theoretical discussion, this book is rooted in the real world, with many chapters including organisational case studies. Although I only bought the book recently, it is already well-thumbed; I recommend it strongly.
