Nancy Kress is the author of twenty-two novels and numerous short stories. She is perhaps best known for the “Sleepless” trilogy that began with BEGGARS IN SPAIN. Her fiction has won four Nebulas, two Hugos, a Sturgeon, and the 2003 John W. Campbell Award (for PROBABILITY SPACE).

These two outstanding stories give us a fascinating look into the evolution of artificial intelligence and the impact it has on human society.
