In 1988, Benjamin Franklin Smith suffers a massive coronary and is placed into cryonic suspension, igniting a storm of controversy among his suspicious relatives. In 2072, on his 147th birthday, he is reanimated by his great-grandson, rejoining a world in which such procedures--along with eugenic selection, virtual reality, and nanotechnology--have become commonplace. Ben's friends, children, grandchildren ,and mother are also given second chances in this brave new world; technology has even made it possible for Ben to have his dead wife cloned as an infant, raised by their son (also frozen and revived) to an adulthood in which she marries him again.
