Dr. Kathleen Sainsbury, head of an independent research facility, has been experimenting with a gene sequence that allows fruit flies to live three times longer than normal. But what she really wants to find is that same type of longevity gene sequence for humans. When she's unexpectedly given the element that could lead to that breakthrough, the results are catastrophic, in more ways than ever imaginable.

The progression and culmination of this story's intriguing premise did not quite live up to my expectations. It starts off very interesting with a good backstory and the promise of a great scientific thriller posing moral questions of biblical proportions. However, present-day character interaction detracts from an otherwise fascinating hypothesis of finding a gene sequence that can prolong life and the consequences of that discovery. THE GENESIS KEY is still a good read for those interested in this scientific topic.
