Forgot to post my review. First, it wasn't bad. That having been said, it was Crichton's worst - by FAR.
Crichton spent way too much time going over and over his reasons for disagreeing with the current world view on global warming. He often interrupted interesting plot developments to go over it again, from a different angle. I found this extremely annoying, and I agreed with his view before even picking up the book.
While I am glad that I read it, I am sorry that I paid $20 for the hardcover. Should have waited for the paperback...
