The author is a practicing neurosurgeon, one of only two hundred or so women in this specialty which numbers about 4,500. She was the first woman to be admitted to her neurosurgery residency program. Her father was a surgeon and she was definitely influenced by him and says that, as the oldest of four children, it was always expected that she would become a doctor; but she didn't decide for sure until partway through her second year of college.

Once in medical school her decision for neurosurgery as her specialty came very easily. Oliver Sacks's writing had a significant influence on her decision. She was also influenced by her college sweetheart who became her husband and who also chose to train as a neurosurgeon. He is not practicing now and they do not have children.

Her description of her long years of training are interestingly related with many individual patient stories and also many descriptions of her teachers and peers. She takes time to describe how she views the specialty itself and its power structure and all that entails. Among the interesting chapters are two about her research years, one at the center for cognitive brain imaging at Carnegie-Mellon and one as a fellow in Epilepsy Surgery. The author was fascinated with the complexity of brain function and its relation to anatomical structure with which she was much more familiar.

Firlik found that she loved "life on the learning curve" and that her curiosity was broad. About her last year as Chief Resident she said "I have had my hand in saving lives and I have had my hand in helping to end them: I'm not talking about murder, of course. I am talking about helping people die" (227). She was able to write this book because she kept a journal during her training.
