I have a book called ! "Multiple Selves, Multiple Voices" by Phil Mollon.

It is written evidently for a student of psychiatry and as such doesn't seem to be very informative for either those whom are looking for self help. It clues you in on some of the mechanism involved, but again I think personal experience can speak for itself in the learning / healing process in a better way than this book can.

I may be being overly critical though... Seeing that I actually dissociate when reading the book it makes it hard to retain the information or to come to a safe conclusion!
