I'm not sure how much use this would be, because it would have to work in the form of rules. We seem to be generally quite good with rules. Where things go wrong for us is in dealing with context, and that's why a book won't help, because it can't possibly say what to do in every context. The reason why I have issues with the NT world is that it's based around inconsistent rules, like "Honesty is the best policy. . . except when it isn't." It's instinct and intuition in social situations which is lacking. I don't see how a book can really help with that.
