On our Book Reviews board you will find various books recommended but I believe the book you're referencing is
Splitting. The full title is
Splitting: Protecting Yourself While Divorcing Someone with Borderline or Narcissistic Personality Disorder by Bill Eddy and Randi Kreger and is available at their websites HighConflictInstitute, BPDCentral and also other bookstores including Amazon.
Bill Eddy has other books on his site such as High Conflict People In Legal Disputes, the newer software
HCI PatternViewer For Parenting Disputes In Divorce and even a video presentation of his weekend seminars designed for lawyers, judges, social workers and other professionals.
Amazingly, many lawyers will pooh-pooh the idea of reading a book, they'll figure they know from their college classes and past cases how to do it. So it helps to have books written by a socialworker/lawyer/mediator/author for the professionals and yet still quite readable for us. How to get your lawyer to read it for strategies in black and white that work? Hmm, that's much harder and another issue for each of us as clients.
