Well, that's not entirely accurate. You're presenting the book's subject matter in support of therapist negative intention as though the goal is to retaliate and punish clients, or that it's an expose of how therapists engage in such behavior. I'm waiting for this title to be available on Kindle, but I am familiar with other works by Safran and Muran, and their interests are in the role of clinical training and its relationship to the avoidance/resolution of ruptures in order to increase successful therapy outcomes. In pursuit of that, they usually do examine therapy rupture case studies in order to better understand how ruptures develop and provide possible interventions.
