My mother and I read this together, when we realized that she and I, and my sisters and I, were having the same arguments over and over. It was incredibly helpful. This book presents the common patterns we use when we are angry, and points out the flaws in each one. Once we were aware of the patterns, we would watch for them, and it made it so much easier to avoid needless fighting. And when two people were arguing about something, this book allowed the others to step back and not escalate the fight. (She presents several patterns that involve using a third person to escalate the fight in some way. Just think how much easier fights would be if your mother-in-law or child or sibling or whatever stayed out of it.)

This book didn't end all fighting, of course, and I'm not sure it would work so well if only one person has read it. But it was immensely helpful for our family.
