The Dark Lady: A Romance of the Far Future

She was old when the world was young. Her image appears in painting from before the Renaissance - but also from the Earth of 3,000 years from now, and from a dozen or more far-flung worlds around the galaxy. Who is she, and what is her secret? It remains for an alien art critic named Leonardo by his human associates to find the answer, and to put himself, his friends, and even some of those worlds at risk in the process. This is the legendary novel by multiple Hugo winner Mike Resnick that became the only American winner of France's coveted Prix Tour Eiffel and its 100,000-franc grand prize.
