This trilogy basically centers around "What if there was a group of people who didn't need to sleep?" From there, she explores what's good about being different, and what's really bad about being different. I found all three books to be fascinating and very entertaining.

"FROM THE PUBLISHER
Kress, a writer who has been appropriately compared to H.G. Wells and Aldous Huxley, deals with evolutionary forces, genetic engineering, technological progress, and social and class conflict, confronting enduring issues that face human society in this century and the next. The Sleepless and the SuperSleepless, two generations of genetically modified superhumans, are now in conflict with each other, and with the spectrum of normal humanity, whose radical division into the rich and poor has made a parody of democracy in the twenty-second century. Human civilization has been transformed. Now it may be destroyed. And if it falls, what kind of world is left, what kind of humanity?"
