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 is killed 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 paleo-botanist and like Alan Grant is among the first people to tour Jurassic Park. Tim who is the 11-year-old grandson of John Hammond, he is kind of geeky, into computers and loves dinosaurs. His seven year-old sister is Alexis, she has a kind of tomboy attitude and loves baseball. Ian Malcolm is the Mathematician that uses the Chaos Theory to predict disastrous results. Finally there is Dennis Nedry. He was the computer genius whom greed and ambition brought chaos to Jurassic Park. There are many other characters that played a big part in the book, but I thought they were the best and the plot revolved around them. The characters show the greatest difference in the movie and the book. There were many opposites in the characters and even the roles and elements 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. Denis Nedry took 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. All hell breaks loose when the humans try to warn a boat that it's transporting Dinosaurs to the mainland, and run away from them at the same time. .
4. 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.
