In 21st-century America, genetic engineering makes it possible for those who can afford it to become parents of improved, custom-made babies. The controversial procedure has produced a new breed that can function without sleep. Leisha Camden, daughter of a wealthy industrialist, is one of "the sleepless," who are endowed with remarkable intelligence and other genetic enhancements. A generation of prodigies, Leisha and her peers are resented by the rest of the population, who begin to persecute them. To escape violence, the Sleepless retreat to an armed camp, the Sanctuary, where for decades they fight to legitimize their existence in an increasingly hostile society. Leisha, a brilliant, idealistic lawyer, finds herself ostracized by both Sleepers and Sleepless as she struggles to bridge the widening gulf between the two groups. Meanwhile, the Sleepless must learn to deal with the prodigies among them. Kress competently handles a well-worn science fiction concept and raises some intriguing scientific and sociological issues.
