The science in this book is pretty good. I know more about the subjects than someone off the street, and my bullshitometer didn't redline once. I could tell where the truth got blurry, but there was no "and then we exceed the speed of light with a Chevy engine and some biodiesel!" moment of pure impossibility.
Michael Crichton novels are all written with an eye to being a movie, I'm sure. This is no exception--Fox snagged the rights before the book was even published. The book has the usual thriller moments of narrow escape, renewed fear, and ingenious escape, and makes for a good read as well as (inevitably) a good view. I consumed it as soon as I bought it, and recommend it just as quickly.
