NANCY KRESS has won both the Hugo and Nebula Awards for various pieces of short fiction. She lives in Silver Spring, Maryland, with her husband, SF author Charles Sheffield.

In the early nineties, Nancy Kress took the SF world by storm with her multiple award-winning novella, "Beggars in Spain," which became the basis for her extremely successful Sleepless Trilogy (comprising Beggars in Spain, Beggars and Choosers, and Beggars Ride). Since then she has written more than a dozen novels, most recently the well-received Probability Trilogy, which Booklist praised saying "Kress's characterizations are as sound as ever, but many will be agreeably surprised at her proficiency with military hardware and action scenes. Very impressive."And Kirkus, in a starred review, simply raved: "Kress's always excellent characters wrestle with a splendid array of puzzles and problems, human, alien, and scientific: another resounding success for this talented sure-footed writer."
