Query: Classic Crichton at its best.

I love Michael Crichton. I have read nearly all of his books, and this stands out as one of his very best. For everybody that ever took interest in science, you will adore this book. I was sleepless for several nights after reading this book, exploring the possibilities. Even if you hate Sci-Fi, this book will be enormously entertainning because of the master storyteller in Crichton. This is a great book and I highly recommend it to every type of reader.
