I listened to the audio version of this book.
It is a short listen with some good practical examples and principles. I think the principles here are good starters for conflict resolution. There is some parallel (though from a different perspective) between this and "Anger...powerful emotion".
Both are good but I think many situations in this book quickly cross over into the Anger book making both of them important resources.
I am struck by his clear articulation of where we have problems. Some of the biggest problems are a result of not having proper examples as we mature. Understanding the root cause is only the beginning of recovery and these techniques will take much practice (lifelong practice) to become Christ-like.
