Crichton uses straightforward prose, neither eloquent nor overly colloquial. He relies on content more than nuances of language to tell his story, and in this is an excellent communicator. In a romantic novel, this style would come off rather bland, but it serves the science fiction and techno-thriller genres well, where the development of concepts trumps the development of characters. The only unusual language is some laborious - and largely unpronounceable - technical terms, sprinkled in for effect.
