@rysiek Well, the novel qualifies, but lots of interesting stuff was left out in the movie.
For instance there's this one exchange between Nedry (the evil programmer) and an acquaintance who goes "That company needs multiple Cray XMP!? WTF are they doing?"
Also I think BioSyn (the InGen competitor bribing Nedry) isn't even mentioned in the movies and they were completely thrown out in JP2.
If you're ever in need of techno thriller novels, I definitely recommend the two Jurassic Park books. :)
