This Hugo and Nebula Award winning story is a modern day science fiction classic.

This coming of age tale follows Leisha Camden. She is the first person genetically altered before birth so that she does not need to sleep. Her rich industrialist father pays for the procedure so that his daughter will have a competitive edge over others. It's soon discovered that Leisha's mother is also carrying a "normal" child. As Leisha grows older she finds others who've had the non-sleep genetic alteration. Compared to their age mates, the non-sleep children, who have not had I.Q. genetic manipulation, are more intelligent, better at problem-solving, and more joyous than non-engineered children. And no negative side effects reported so far.
