You've all seen the film (if you haven't then what are you doing on here?), but have you read the book it's based on?
Written 3 years before the films' release, this is the original account of what happened on the small island of Isla Nublar, 120km south-west of Costa Rica. The plot is mostly the same, the characters are just about there, and while there are some slightly different dinosaurs, the main cast is still alive and kicking. Definitely worth a read.
