Rating: 9/10
Frankly speaking, I think the first novel was way better. What I liked about this novel, though, was the fact that it wasn't using too scientific terms and that the suspense is really alive. While reading it, I felt like I was really there, hearing the giant steps and feeling the ground shake. All together, its a pretty nice novel.
I'm looking forward to reading more of Crichton's works in the future.
