Query: Close, but no Jurassic Park

Michael Crichton has been disappointing me of late. Did anyone actually make it through Airframe? But this is one of the better books he's written in quite a while. It has a great premise and I was intrigued by his explanation of time travel. The Middle Ages is one of my favorite eras in history and I was excited about this book. It was a pretty good read but I thought his characters were too shallow. I didn't really care if they found what they were looking for and came back or not. He had a really good idea, but he took it for a walk instead of a run.
