I read this book out of curiosity and was taken by how much of it makes sense and I could identify with. You do not have to be a child of alcoholics or married to a substace abuser to relate to these stories.
There are controlling, manipulating folks out there which can affect ones life.
There is another book: Book Title: Healing the Shame That Binds You
Author: By John Bradshaw
I am reading now and it is also an excellent book on the subject. I have not finished reading it, but it has grabbed my attention so far.
