This book should have been a New York Times Best Seller. As far as I know it did not make that list. But the plot is great, the biotechnology is great, and the plot twists at the end are excellent. A slightly better way, or more plausible theory, for memory transfer should have been come up with. It was not really scientifically plausible. A little better editor and better science and this would have been a perfect book. ( )
