The book was a quick, easy read, but some details were lacking. The author is a teacher and does not have a medical background. Therefore, the book is riddled with medical and scientific errors. For example, one patient lost his vision completely because of pressure on his “optic nerve.” In reality, pressure on an optic nerve would cause a deficit in only half of the field of vision. As a physician, I found these errors distracting, and it was very difficult to get swept away by the story. Instead, I was constantly trying to use my imagination to pretend the body functioned in the way it was written in the book.
