Congo - Michael Crichton This is the first Michael Crichton book I have read in some time. I had greatly enjoyed all of his previous books, but this one fell short of my expectations. I had seen the movie made from this book a couple of times before, and although the book was very different, I think it ruined the suspense of the story a great deal. Also, this book was published in 1980 and Crichton spends a lot of time explaining technological advances. We have come so far since then that there was no excitement in it for me. All in all, not one of the author's best efforts and a disappointment.
