It has easily been the best book I have read this year. That's really a good enough recommendation though as I have read some fairly poor / true pulp this year. I brought this book to Cyprus with me and I found I could not put it down Cool technology and a wicked story left me dying for more at the end. I would say that any fan of Sci-Fi should definitely have this on their wish list.
My next book I am reading (another from the SF Masterworks collection) is The Shrinking Man by Richard Matheson. I am a couple of chapters in and am gripped so far. A couple of good books are really what I need to get my passion back.?
