Beggars in spain - nancy kress

In a world where the slightest edge can mean the difference between success and failure, Leisha Camden is beautiful, extraordinarily intelligent .

and one of an ever-growing number of human beings who have been genetically modified to never require sleep.

Once considered interesting anomalies, now Leisha and the other Sleepless are outcasts -- victims of blind hatred, political repression, and shocking mob violence meant to drive them from human society .

and, ultimately, from Earth itself.

But Leisha Camden has chosen to remain behind in a world that envies and fears her gift -- a world marked for destruction in a devastating conspiracy of freedom .

and revenge.
