This book was really good until the team went back in time. After that it became way to predictable and repetitive. The team gets caught, they run away, they get caught, they run away, and so on. I found myself skimming pages because I knew what was going to happen next. One could almost get away with just reading the last sentence of the chapter and not miss anything. Crichton does have his awesome moments but in this book they faded away in time... sort of speak.
