Great book, very dissapointed with the ending though...it amde me feel like I had read 500 pages and then been deprived of the amazing ending it deserved.  Oh well, still a great read, puts the movies into a whole new perspective.

the book is different to the movie?

Of course there are similarities but the book is waaaaaaay better.  It actually helps tho to of seen the film before hand because when reading the book you can picture the charachters from the film saying whats in the book and stuff.  Really good book tho, it goes into more 10x more depth about Jurrasic Park than in the film.
