The novel of Jurassic Park is a thrilling ride and an experience that everyone should read. The Book is very different from the movie counterpart in many ways. 

For example some of the dinosaurs in the book are different from the movie. The Dilophosaurus in the movie is small with a green body and had a thrill around its neck but in the book the Dilophosaurus is ten feet tall and with a yellow body with leopard patterning. 

Other details in the book are that the book is more graphic than the movie. Going back to the Dilophosaurus example in the movie Dennis Nedry was killed off screen by the Dilophosaurus but in the novel his death was more gruesome then the movie version.

Other details in the novel is that some of the main characters die then in the movie, even characters that are not in the movie, and the story ends very differently then the movie.
