Dr. Marie Heaton is an anesthesiologist at the height of her profession. She has worked, lived and breathed her career since medical school, and she now practices at a top Seattle 
hospital. Marie has carefully constructed and constricted her life according to empirical truths, to the science and art of medicine. But when her tried-and-true formula suddenly deserts her during a routine surgery, she must explain the nightmarish operating room disaster and face the resulting malpractice suit.
