12 Steps for the Recovering Pharisee (like me): Finding Grace to Live Unmasked, John Fischer, 2000.
This book uses a somewhat tongue-in-cheek 12-step model for recovery from the spiritually deadly disease of performance based righteousness and elitism. The medicine goes down smoothly with a healthy dose of humor.
