Excellent book on the collaborative process of the patient and physician.Well told, avoiding the usual traps of the genre, he captures well the balance between the knowing and the unknown that is at the heart of the search for the process we need to go forward.Kind, wise and relevant to all parties in the situation.Reading it made me feel like I had one of my attendings as a patient, and we were both scared for all the right reasons,with a few extra ones, just to be safe.
