Dr Alison Miller is a Canadian Psychologist. She developed the LIFE (Living in Families Effectively) Seminars for parent education. Since 1990 she has specialized in treating survivors of organized criminal abuse.
Nothing is better than attending seminars with Allison Rees, but this book has on paper a lot of what you learn from her in the sessions. Very helpful, and also encouraging--highly recommended for any parent wondering if they are doing things right.
