is this real? who knows. everywhere i look online classifies this as a nonfiction book, a real account. But if you Google the first person to use multiple personality as a defense in court, its actually a guy named Billy in 1978. A year after this book is published.  Moving on from that, after a while this became a boring read. It was the same pattern over and over of Johnny ruining stuff. Once you get past Henrys terrible childhood and relationship with his abusive dad there isn't much of interest.
