BEWARE!!! Double check before you make final purchase that is is Michael Crichton and not Riva Castleman. Riva wrote a book by the same name. The place I bought it from would not responde to me when I tried to return it.
I bought this book to finish my Michael Crichton collection. Once I got it in the mail I was extreamly bummed to find a diffrent book written by a diffrent author. I dont know if the MC version is good or not, it probbaly is, maybe one day I will actually get it. I am wary of buying this book online though as I dont want the same scenario happening again.
