Query: Worthy sequel of 2001

Frankly, this book is not as great as 2001: A Space Odyssey. In fact, I wonder if anybook can match 2001. Still, I loved this book as a fiction, and I read it several times. This book has almost everything that one can ask. ps: you may read 2061, but NEVER read 3001! I think Arthur C. Clarke was blackmailed to write this book.
