Read Dan's review here. This is what I said about the book in my endorsement.
“There is no more common or urgent pastoral need in the church today than to cultivate the Gospel practice of forgiveness. Christians need to know what the Bible teaches and live it out, radically. Unpacking Forgiveness: Biblical Answers for Complex Questions and Deep Wounds is an engaging, convicting but emphatically encouraging treatment of this hugely important (and sometimes mindbogglingly challenging) part of life. Dr. Brauns writes from the standpoint of a faithful, wise, experienced and caring pastor who has seen the heartbreak of an unforgiving spirit at work in the lives of people, but also the power of grace in the hearts of Christians who have learned to forgive and be forgiven.”
