Some see it as the greatest scientific breakthrough in the history of medical research. Others as a blasphemous attempt to play God. At a corporate lab in Connecticut, researchers have pioneered an amazing genetic technique that can regenerate functioning organs inside the human body. The medical implications are staggering: Could humankind become immortal? Now, in a worldwide media spotlight, an unprecedented "science court" has been convened in Washington, D.C. Its mandate is to hear the evidence and decide whether or not the experiments should be allowed to continue.On opposite sides of the courtroom stand two brothers. Dr. Arthur Marshak is the brilliant director of Grenford Laboratory who sees his work in organ regeneration as the crowning achievement of his career, a chance at the Nobel Prize, and a momentous gift to humanity. His younger brother, Dr. Jessie Marshak, is a physician, humanitarian, and idealist who sees the imperfect technique as unethical at best, elitist by implication, and dangerous at worst. And standing between them is Julia Marshak, a remarkable, beautiful woman who broke one brother's heart and married the other.
