David Myers is a young neurosurgeon willing to bend the rules to join the elite group of researchers who dominate the emerging field of gene therapy. But just when success is within reach, his cherished career is threatened. It becomes clear that someone else has been bending the rules-on him. As he searches frantically for an explanation, he discovers a terrible secret. He and his family have been unwitting subjects in a fifty year-old genetic experiment. And unless he can unravel the mystery, none of them-least of all Dr. David Myers-are safe.
