Query: Slow start, nail biting finish

This was a very exciting book. A real nail biter to the end. Unfortunately, it took over 100 pages to get started, but Crichton is such a good writer it didn't matter to much. I found myself gasping and throwing up my hands every time the historians got into another situation. It kept me on the edge of my chair, and I agreed with the ending.
