A surprisingly insightful guide to New Age treatments.

Beginning with a seminar where a 100 people with name badges learn to "share", Isabel takes up "Rolfing", joins a nude Goddess workshop, a weekend of Tantric sex, re-birthing and reincarnation sessions, not to mention a spot of colonic irrigation. Her mind, body and spirit challenges vary from ta'i chi to astrology, anger release to convent retreat, hypnotism to Co-Dependents Anonymous.
