George Galen is a brilliant scientist, a pioneer in gene therapy. But Galen is dangerously insane. He has created a method to alter human DNA, not just to heal diseases, but also to “improve” people: make them stronger, make them able to heal more quickly…and make them compliant to his will.

Frank Hartman is also a brilliant virologist, working for the government’s ultra-secret biohazard agency. He has discovered how to neutralize Galen’s DNA-changing virus. Now he is the one man who stands in the way of Galen’s plan to "improve" the entire human race.

This taut thriller takes the listener a few years into the future and shows the promise and danger of new genetic medicine techniques.
