Great and unnerving at the same time, the book is filled with various studies in the field of social psychology. I cannot recommend this book too highly; an entertaining and informative read. If you've ever been snookered into buying a copy of the Bhagavad-Gita in a bus station or found yourself purchasing a timeshare condo against your better judgement (or the thousand other unneeded sales we've all been hit with at some time or another), this book is for you. It gives a structure to the various cultural instincts we have and how these can be subverted. On a more positive note, it is also useful for understanding how to best get your own message across (while avoiding being manipulative). For example, after reading it I now tell my children "clean your room, because...", as using "because" makes the request more effective (oddly enough, regardless of the reason given after the word "because", at least in theory. I haven't tried "because the moon is full" yet). I plan to give this book to my children when they graduate from high school (if not sooner).
