Query: A good book, but it should have and could have been better.

The Lost World is a sequel to Jurassic Park. What happens to the characters, especially Malcolm, is almost the same as the first book. If you liked Jurassic Park then you will like The Lost World. However, you may be a little disappointed because it could have been better if Crichton had tried a little harder to create a story and not to make money
