In the year 2276, Duncan Makenzie travels from Saturns moon, Titan, to Earth as a diplomatic envoy to the United States. As a member of Titans First Family descended from the moons original settlers 500 years before, Duncan finds himself welcomed into the glittering political and social scene in Washington.

But Duncan isnt just on Earth for a diplomatic visit. Haunted by the memory of a woman from Earth he once loved, Duncan is also driven by the need to continue the family line-despite a devastating genetic defect. A tour-de-force of vivid characterization, futuristic vision, and suspense, Imperial Earth is one of Arthur C. Clarkes most ambitious novels.
