Not only does Crichton give a fabulous story but also incorporates into it the profound ideas and lessons of psychology and space. The fact mixed with the fictional story makes it all very realistic. the story is given from the point of view of a normal man, who has no idea what is going on. we only realise something in the story when he does. The plot twists and turns and when you finally think you have cracked it, it twists again. A stunning novel which I could not put down until I finished the last page. I havent yet seen the film, perhaps this is why I found the book so good, because my views had not been spoilt by the film. If you are into sci-fi, the mind, and the unknown, then PLEASE read this book. I cant give it enough praise.
