Kress, Nancy. Beggars Ride. New York: Tor, 12/1997. 406pp.
Nancy Kress is one of the best sf writers going these days and she proves it with the finale to her Sleepless trilogy. In a world where people are divided into various camps, ranging from the Donkeys (the powerless, nomadic common people) all the way up to the genetically altered Supersleepless who have many times the intelligence of regular humans and need no sleep, a huge confrontation is shaping up for control of the genetic destiny of the human race. Who will win this Darwinian struggle for survival of the most genetically fit? Tune in to the trilogy and find out. This is definately a case where you have to read the earlier volumes for any of this to make sense; they are Beggars in Spain and Beggars and Choosers.
