So often what you think you know may not be so. And it's a reason I love the book just out from America's top-selling thriller writer, Michael Crichton. He's the man who created the popular TV medical drama "ER," wrote "Jurassic Park," which ranks among the top 10 grossing films of all time, and much more. Crichton's books and movies have grossed more than $4 billion. Now, he's tackling global warming in his latest techno-thriller, "State of Fear."
