A billionaire has created a technique to clone dinosaurs. From the left behind DNA that his crack team of scientists and experts extract he is able to grow the dinosaurs in labs and lock them up on an island behind electrified fences. He has created a sort of theme park on the island which is located off the west coast of Costa Rica. The island is called Isla Nublar. He plans to have the entire planet come and visit his wondrous marvels. He asks a group of scientists from several different fields to come and view the park, but something terribly goes wrong when a worker on the island turns against him and shuts down the power.
The main characters in the book are: John Hammond who is a billionaire developer who has used his resources to create the dinosaur filled island known as Jurassic Park. He is an old grandfather, and he dies in the book by a dinosaur known as a Procompsognathus. Dr. Alan Grant who is a renowned paleontologist, agrees to visit Jurassic Park only to find out it is the home of several Dinosaurs. Unlike the movie Dr. Grant loves kids in the book. Dr. Ellie Sattler is a Paleobotinist and Alan Grant who is among the first people to tour Jurassic Park. Tim who is the 11 year old grandson of John Hammond is very into computers and loves Dinosaurs. His 7 year older sister is Alexis. She has a kind of tomboy attitude and loves baseball. Ian Malcom is the Mathematician that uses “Chaos Theory” to predict disastrous results. Finally there is Dennis Nedry. He was the computer genius who’s greed and ambition bring chaos to Jurassic Park. The characters show the greatest difference in the movie and the book. There were many opposites in the characters. One of the obvious differences is that the roles of Tim and Lex were reversed.
The book starts off when some of the dinosaurs have escaped form the island. John Hammond invites a group of scientists to the park. He also invites his grandchildren. While all of this is happening Denis Nedry ends up taking a bribe from a rival company to get samples of Dinosaur DNA. In order to make his escape, he turns the power off, even the electric fences. Some of the chaos starts when the humans try warning a boat that they are transporting dinosaurs to the mainland.
