It says something about a book when practically every review on Amazon is one in which the reviewer has nothing but good things to say about it.I read this book for the first time many years ago - probably not too long after it first came out (in 1987). Since that time I've re-read it numerous times, I've recommended it to relatives and friends, and every couple of years when I want to relax and enjoy a light read, I pull it down from the bookshelf. and enjoy it once again.Here is the thing about this book. There have been quite a few novels written about invisibility, including of course classics such as The Invisible Man, but I don't think that any of them has dealt with the practical downsides of invisibility in such a clever way, and with quite the wit and playfulness as did H.F. Saint, while at the same time creating a story with real tension and suspense.The main character, Nick Halloway, is a stock analyst with just the right measure of irreverence and charm. The descriptions of the practical aspects of Nick dealing with his invisibility - imagine eating something and then watching as it makes its way down into your stomach and then slowly is digested into nothingness!! All of a sudden your invisibility is compromised by this very disgusting and visible remnant of your most recent meal! A very obvious disadvantage to invisibility, that, now that it is pointed out to us!Combine that with the Conspiracy Theory aspect of government agents relentlessly hunting down poor Nick, who simply wants to be left alone.And the icing on the cake is the development of Nick's adaptation to living with invisibility - how to live and survive; learning to use his Wall Street financial analyst experience, combined with his invisibility, to spy on businessmen as they work to put M&A and other deals together, and use that information to speculate on the affected stocks and reap quick profits at essentially no risk. (Let's be honest, how is the poor guy supposed to survive, after all? He can't exactly continue to work at his old job, can he?)In fact, I like this darn thing so much that I have two copies! I couldn't find my original copy for quite a while, and finally in desperation I went to Amazon and purchased another (used of course, since it is no longer available in print) in order to get my fix! Some months later I finally come across my original copy, so at least now I have an extra to loan out, without worrying that it will never get returned.Forget about the movie. As other reviewers have mentioned, that Chevy Chase escapade is nothing in comparison to this book.The tragedy is that the movie is still available for purchase, but the book is out of print. This is a very entertaining and enjoyable book to read.
