This book is unique in two ways: It takes one's anger seriously, looking into its possible causes. And it does not isolate the angry person, but helps rebuild damaged relationships. It must be noted that this book is written by a Christian (Protestant) family counsellor, with Biblical illustrations. It's very easy to listen to, if Christian references don't bother you. It is very general, honest about its context, and can be appropriated by non-Christians too. This book is first of all about fixing relationships and learning to communicate in stressful situations, not about breathing exercises or meditation in solitude.
This book has a great selection of authors and cases to reflect upon. NOT a book one can listen to in one sitting.
It's like an encyclopaedia really. You either have to know what you're looking for, or listen through everything and create bookmarks of the parts that you're most interested in, so that you can go back to them later.
