This story left me unsettled and I like that in a book. Scenes from this tale still haunt my waking hours as well as my dreams. The vision of a society without sleep, hallucinating and confused, and having it in for those who can still sleep, is nightmarish and even apocalyptic. At times the story seems disjointed, but that only adds to the feel of jittery edginess that accompanies this tale of insomnia.
