Like many other books by author Michael Crichton, this book is a fascinating thriller regarding some aspect of technology gone wrong... in this case, cloning dinosaurs.
Most everyone has at least seen the smash hit movie, so I won't go into too much detail. Basically, a scientist clones dinosaurs on an isolated island in the hopes of turning it into the world's most amazing theme park/zoo. But everything falls apart when a scheming computer programmer disables the park systems while stealing dinosaur embryos to sell.
All in all, it's a great book. But there's a major flaw... two of the heros are kids. If you've seen the movie, you know who you're probably expecting... two fairly smart, nice kids who end up being chased by dinosaurs. The problem is, they're a brother and sister. And the sister, Lex, is a complete and total brat. I won't go into details of the scene where she's whining for ice cream when they're hiding from raptors in a cafeteria. By the end of the book you want to feed her to raptors.
If Lex was more like she was in the movie, or completely cut from the book, it would be a five-star book as besides for that flaw it's a great book.
