First of all, I'd like to express my sympathy to any parent who, faced with hostile ex's (and/or their new partners) is even contemplating reading a book like this. I simply can not describe the personal feeling upon hearing your child speaking negatively about you in tonalities and inflections which clearly aren't theirs. If you are new and inexperienced to the subject of parental alienation, and your child has expressed symptoms, your natural reaction, after total and utter shock, will most probably be anger - this book will teach you how to deal with these negative emotions, and how to react positively (thereby not pushing the child away, and validating the ex's/ex's new partners poison).
This book was recommended to me by a member of FNF, and I can confirm that, at the moment, this is probably the best tool you can have against parental alienation. It will alleviate the feeling of helplessness and anger, and provide priceless tips and tools to counter the damaging effects on your child. If you are seeing the symptoms, no matter how minor and seemingly insignificant, get this book before it's too late.
