I loved CONGO, very much. It is extreamly suspensful and well written. It is about a tour guide person named Munro, Karen Ross, from a compony called ETRS, and Peter Elliot, with the gorilla, Amy which he tought sign language going to the Congo to look for the lost city of Zinj where there are specific diamonds called type IIb diamonds. They discover a new type of gorilla on the way and could prevent a World War III with these diamonds. It is funny because of all the "top of the line" computer equiptment which they talk about (the book was written in 1980). But anyway, there is a part in the book where everything is lost. EVERYTHING! The team can't take credit for finding ANYTHING. The book got exiting again but I was so disappointed that I dropped the 5th star I was about the give the book. The end also kind of dropped short. You were stuck, you wanted to know more but you couldn't. Besides tese 2 problems, this is one of the best books I have ever read!
