This book is filled with constant action. Just when you think the characters are safe, something else happens. It almost got to a point where it was a little over-the-top in the middle, but I think that was Crichton's point. This is a pirate adventure story filled with fighting, kidnapping, murder, treasure and more. I couldn't put it down, and for the most part, I really enjoyed it, and its colourful characters. I give it 4 stars.
