This is a very suspenseful read, both educational and intriguing. Haven't read any other novels by Preston and Child, but certainly will be looking out for more by them. I have given 4 stars - maybe 3.5 was all it deserved, but that is not an option. The Authors should look to see if they can improve their grammar and spelling - most noticeably 'shined' instead of 'shone'. The suspense was real and built as the story progressed, to the last page. A good read which included information regarding genetics to computer wizardry - not all of it correct however, but interestingly entwined into the plot of this story.
