Palaeontologists Dr. Alan Grant and Dr. Ellie Sattler, chaos mathematician Dr. Ian Malcolm and lawyer Donald Gennaro are invited by Hammond to his resort island off Costa Rica. To their astonishment, they discover that Hammond and his InGen Corporation using fossil DNA, supercomputers and gene sequencers have been able to clone dinosaurs at the Jurassic Park. The group is also joined by Hammond's grandchildren Tim and Lex Murphy. They all set out on a park ride to check out the dinosaurs when all hell breaks loose.

The story in the book is deeper, darker and much different than the movie. I hadn't expected this. It was just as nail-biting as any Crichton book and I ended up being awake until 5AM (and yet another weekend sleep went down the drain). Malcolm with his chaos theory ramblings is highly entertaining. There are more varieties of dinosaurs introduced in the book than in the first movie. Crichton's books always have some smartass way of division into sections. This book is divided into iterations, with each one slowly progressing to form a fractal accompanied by Malcolm's quotes alluding to the same. The underlying message of the book is that genetic engineering without careful understanding of the consequences can be devastating. Though written back in 1990, the book's takes on genetic engineering are surprisingly accurate seen in today's context. This is a good pop sci-fi thriller.
