After reading and enjoying the same author's "5 Love Languages" book I noticed that he had written this one, and I thought it would be equally helpful. It's chock-full of scriptures and other religious themes. Essentially that's his entire method of anger management is from an understanding that even got experienced anger at times.
I dedicated to reading the forward and 1st chapter before sitting this one down. It's getting donated to a church or library now because it actually BEGAN to enrage me that I'd wasted my time and money on such a book. From what I understand from the author is that if you don't believe in God then you cannot work through your anger. This is flawed and bad life advice. Everyone deserves to control their anger, not just Christians.
