Mockingbird by Walter Tevis ($1.99)
In a world where the human population has suffered devastating losses, a handful of survivors cling to what passes for life in a post-apocalyptic, dying landscape. A world where humans wander, drugged and lulled by electronic bliss. A dying world of no children and no art, where reading is forbidden. And a strange love triangle: Spofforth, who runs the world, the most perfect machine ever created, whose only wish is to die; and Paul and Mary Lou, a man and a woman whose passion for each other is the only hope for the future of human beings on earth.*
An elegiac dystopia of mankind coming to terms with its own imminent extinction, Mockingbird was nominated for a Nebula Award for Best Novel.*
