Retreat is an account of the rise of the relationship between the 60s counterculture and wellness, and how this continues to shape social perceptions of health, wellbeing and sprituality. There is a lot of material brought together here and Ingram is a sympathetic but also critical (sometimes, very critical - especially about some of the western Buddhist teachers of the 60s and 70s) observer and participant, but the book isn't quite as good as it could have been because of the sometimes disjointed short chapter format where one thing just follows another.
