Query: Excellent read!

I originally read "The Mote in God's Eye" about 15 yrs ago. I decided to read the followup book listed here. I downloaded it onto my Kindle app, which was a very straightforward process. Makes it very easy to obtain with no waiting. The book was every bit as good as the "Mote. . ." The writing was excellent, as I have found in all books by Niven/Pournelle. Some reviewers have been negative about this book, and I don't understand why. I would recommend it to my friends.
