" Thanks Caroline, for bursting my fantasy bubble with reality. This is another Clive Cussler filled with fantasy, some science?, and adventure. It is a book to kick back with and not have to think. Since I know very little about science and left reality behind long ago I enjoyed the mix of science, winning of battles against all odds, and being chased by ancient Indian tribes deep in South America. Also I was glad to hear that my eight glasses of water a day are safe due to the fearless efforts of Kurt Austin and NUMA. "
