Query: Thoroughly discredited

This book has been thoroughly discredited and should be read only as a cautionary tale of how psychiatry and journalism can manufacture a story from whole cloth, taking advantage of a woman who very well may have been mentally ill, while profiting mightly from the results. This "author" made a fortune from this lie. Shame, shame! Read "Sybil Exposed" instead.
