I can't believe Robin Cook wrote this book. It's not like his other books at all. It's a good book, a little impropable, maybe, but good. Of course, all of his stories are impropable. I don't really like the ending. I mean, what would be so bad about the world ending up like that. I won't spoil it for anyone; I hate it when people do that. I just think the planet would have been it they hadn't stopped "them".
