In this final installment of Nancy Kress' award-winning Beggars trilogy, it is now two hundred years in the future. Regular human beings hate and fear the Sleepless and the SuperSleepless, genetically modified humans who are immune to disease and hunger and do not need to sleep. When the Sleepless plot to take over the world and leave regular humans powerless, civilization and the very meaning of the word "human" hang in the balance.
