I love Michael Crichton. He introduced me to science fiction and, therefore, holds a special place in my heart and on my bookshelves. I've read almost everything he wrote, and I was saddened at his passing. By far, this was my least favorite of his books. It's so bad that it actually mars my opinion of his body of work as a whole. No, it's not the worst book in the world, but it fell well below my expectations.
If you're not familiar with Crichton, please don't start here. Please.
(It's been a while since I read it, and I've tried to block out the details. So please don't ask me for specifics.)
