the other. Plot summary Book I (the original novella) Leisha Camden, born in 2008, is the twenty-first human being to have the genemod for sleeplessness. She is the daughter of one of Yagai's most noted sponsors, financier Roger Camden, who felt he had wasted far too much of his life in sleep, and his wife Elizabeth Camden, an Englishwoman who wanted a normal child. Sleeplessness confers a number of secondary benefits—higher IQ and a sunnier disposition most notably, as well as 50% more productive time (vs the time the unmodified spend asleep); Sleepless not only don't need sleep, they cannot sleep (though they can be knocked unconscious). By the age of fifteen Leisha has become a part of the community of Sleepless, few though there are in the world; she, like all of them, is several grades ahead of her age; the oldest, Kevin Baker, has already become the most wealthy computer software designer since Bill Gates at the age of 16 (in 2020). The first she meets, Richard Keller, becomes her lover; the others become friends and confidants. Two, however, trouble her. One is Tony Indivino, whose mother had problems adjusting to his Sleepless ways and forced him to live as a "Sleeper." Tony advocates a banding-together of all Sleepless in a sort of socio-economic fortress. He predicts that the Sleepers will soon begin to discriminate against Sleepless, and is quickly proved right: a Sleepless athlete is barred from the Olympics, for instance, because her 16-hour practice days are impossible for other competitors to compete with. Likewise some cities forbid Sleepless from running "24-hour" convenience stores. Tony is eventually jailed (for illegal actions on behalf of the Sleepless community), though not before attracting the attention of Jennifer Sharifi, the other person who makes Leisha nervous. The Sleepless daughter of a movie star and an Arab oil tycoon, Jennifer's money purchases land in upstate New York (Cattaraugus County, specifically) to create a Sleepless-only community known as Sanctuary. Finally, Leisha faces rocky relations with her twin sister Alice. By sheer chance, Elizabeth conceived a natural daughter at the same time Leisha was implanted in vitro, resulting in fraternal twins, only one of whom is Sleepless. Alice is constantly in her sister's shadow: "Whatever was yours was yours, and whatever wasn't yours was yours, too. That's the way Daddy set it up. The way he hard-wired it into our genes."
