What if no one had to grow old—or die—ever again? Norman Schuman, a brilliant physician with a Ph.D. in genetic engineering, has successfully reverse-engineered the aging process in animals. Can he do the same for the fifty human volunteers who trust him with their lives as they search for eternal youth?

But someone is determined to prevent Schuman from playing God and will stop at nothing—even murder—to do it. Others intend to steal his Young Again youth formula to use for themselves, or to copy and sell for immense profit.

As Schuman desperately attempts to save his creation, and his life, we learn that for some people, there are reasons beyond vanity that compel them to risk their lives for a second chance at youth.
