This is a fascinating insight into the senses and how their operation can go wrong. Not only does the author explain the medical details of how the senses work, and fail, but also discusses the impact such failures can have on the quality of life of those affected. The case studies are always fascinating and sometimes moving, where the impact on some of the patients’ lives has been intolerable. Throughout the book the author presents a sensitive balance between medical detail and the heartfelt human interest.
