Vulnerable populations Book

I have recently read several books about manipulation and how to deal how to deal with the manipulators in our lives. This book gives lots of practical advice for the layperson, more than I found in other books. I should add that this book confines itself to the everyday type of manipulator rather than the serious antisocial, psychopathic type of individual. In a way, these more mundane types are harder to get a handle on and may therefore cause more chronic, but not necessarily, less important damage. It is crucial to a happy life to learn how to cope with such individuals, especially when they are family members.
