PLEASE NOTE: This is the original novella which won the Hugo and Nebula awards. Leisha Camden is a genetically engineered "Sleepless." Her ability to stay awake all the time has not only made her more productive, but the genetic modifications have also given the "Sleepless" a higher IQ and may even make them immortal. Are they the future of humanity? Or will the small community of "sleepless" be hunted down as freaks by a world that has grown wary of its newest creation?
