Healing the fragmented selves of trauma survivors by Janina Fisher.
There is also a workbook, Transforming the living legacy of trauma, a workbook for survivors and therapists by the same author.
Janina is part of a group of scientists/therapists who work with Bessel van der Kolk (author of "the body keeps the score").
They publish their work via nicabm.com, often their webinars can be watched for free at point of delivery. If you want to re watch, it is very costly, but definitely worth looking out for the freebies and making time for them.
Married to Bumblebear, 3 1/2 kids, a mix of adopted and home-made.
