I highly recommend David Augsburger’s The Freedom of Forgiveness. Also, Philip Yancy’s What’s So Amazing about Grace?, which shows us how God’s forgiveness of us should result in our forgiveness of others. Another good one is Forgive and Forget: Healing the Hurts We Don’t Deserve, by Lewis Smedes. In checking around on Amazon I also found a book called I Should Forgive, but . . .  Finding Release from Anger and Bitterness, by Chuck Lynch. It might be helpful. I also found some good reader reviews of Forgiving Our Parents, Forgiving Ourselves: Healing Adult Children of Dysfunctional Families, by David Stoop.
