In keeping with the format of his hugely popular "The man who mistook his wife for a hat", Oliver Sacks presents his readers with several case stories that are both gripping and enlightening. As always, the author's greatest talent is being able to teach the general reader about the intricacies of the human mind, without reducing the particular patient to something other than human. The people behind each of these case studies are never reduced to being just freaks of nature, but are instead described with a great deal of respect.
I highly recommend all of Dr Sacks' books, but this is the best one to start with if you're new to his work. However, if lengthy footnotes are a pet peeve of yours, you may want to stay away. I, on the other hand, along with many other of his readers, really enjoy the many footnotes as they give his books more depth and points the reader in new interesting directions.
