Anger: Handling a Powerful Emotion in a Healthy Way by Gary Chapman is a must read for everyone, Christian and non-Christian alike, even though it comes at the issue from a Christian perspective. If you have ever hear some of the anger management type psychology stuff going on out there (or seen the movie Anger Management) you may not see the value in examining the topic. Chapman however does do a good job of talking about real situations, and is realistic about solutions. (He does not expect that rephrasing the problem in trendy psychological terms to abolish ones anger issues.) Probably the most two surprising things he says in the book is that anger by itself is not sin and that if someone does not apologize, one need not forgive the offender. Both he backs up as a Christian point of view. There is more to it than that, but I will allow your curiosity bother you a bit so you read the whole book. It is worth the read. The strength in the book is in the pragmatic explanations of what to do. The weakness of the book was the lack of cartoons.
