Query: So bad it has to be a joke!

This would have to rate as one of the worst books I have ever read. Such a great author reduced to such a low level. The book concentrates on techno stuff of the 4th Millennium and that is about it. The characters (if you could call them that) are shallow and offer nothing to this book (if you could call it a book).As Science Fiction it lacks imagination. Which is the fundamental requirement of such an area. Only a small amount of the book is devoted to why it all occurred (the answer). The way this book is written leads me to feel that a 7 year old could understand it. Words with more that two syllables are rarely used and it fails to spark the imagination or the feeling that you are involved in something marvellous. I expected some earth shattering revelation but got crap.I feel this book has now spoiled the earlier experience I had from the other books. As I said I have not read a book as bad as this for many years.
