I was really looking forward to reading this book as I am a big fan of Oliver Sachs. However, the digital formatting is horrible!! I'm missing chapter 1 in its entirety and multiple chapters are truncated followed by error messages on the pages. Capital letters do not align properly with the page and words float on top of one another. I am left wondering which half of the book I actually purchased and what half I am missing! I would NOT recommend buying this book as a download until the EDITOR devotes a little time to formatting the book appropriately for digital download. I am only giving this edition two thumbs down because of the Editor and Company's sloppiness. Oliver Sachs deserves better!

As usual, Sacks examples are extremely entertaining and, well, believable! Big gripe though--my copy was filled with mid-sentence, abrupt chapter endings and tiny bottom parts of words at page top and "phantom" tops of words on page bottoms. I am NOT hallucinating!

As usual, Dr. Sacks delivers with a book full of intriguing accounts that describe different mechanisms of the human mind. It's an awesome book that´s both not too technical so that the layman who is interested in neuroscience can enjoy the read and for those more keen to deepen their knowledge through academic research - since this book gives a great amount of starting points. For those who, like myself, have read a few books by Dr. Sacks before will see a good deal of repetition as he reutilizes cases he already told in previously published books, but the fun is not taken away just because of that. One thing though that could be better worked by his editor is the order in which the cases are presented. It looks backwards to me. The book begins with the most intriguing and fantastic stories, then gradually fades off in direction of more simple and less interesting cases. Great reading nonetheless.

I found it interesting, and a little disturbing, how many different ways people can hallucinate without being mentally ill. The author is a little heavy on the jargon. I used the dictionary a lot while reading this book.

Fantastic read! Love love love this book!
