Rails must be freshly laid ahead of the city & carefully removed in its wake. Rivers & mountains present nearly insurmountable challenges to the ingenuity of the city's engineers. But if the city does not move, it will fall farther & farther behind the optimum & into the crushing gravitational field that has transformed life on Earth. The only alternative to progress is death. The secret directorate that governs the city makes sure that its inhabitants know nothing of this. Raised in common in creches, nurtured on synthetic food, prevented above all from venturing outside the closed circuit of the city, they're carefully sheltered from the dire necessities that have come to define human existence. Yet the city is in crisis. People are growing restive. The population is dwindling. The rulers know that, for all their efforts, slowly but surely the city is slipping ever farther behind the optimum. Helward Mann is a member of the city's elite. Better than anyone, he knows how tenuous is the city's continued existence. But the world he's about to discover is infinitely stranger than the strange world he believes he knows so well.

    The novella “A Necessary Being” showcases Octavia E. Butler’s ability to create alien yet fully believable “others.” Tahneh’s father was a Hao, one of a dwindling race whose leadership abilities render them so valuable that their members are captured and forced to govern. When her father dies, Tahneh steps into his place, both chief and prisoner, and for twenty years has ruled without ever meeting another of her kind. She bears her loneliness privately until the day that a Hao youth is spotted wandering into her territory. As her warriors sharpen their weapons, Tahneh must choose between imprisoning the newcomer—and living the rest of her life alone. The second story in this volume, “Childfinder,” was commissioned by Harlan Ellison for his legendary (and never-published) anthology The Last Dangerous Visions™. A disaffected telepath connects with a young girl in a desperate attempt to help her harness her growing powers. But in the richly evocative fiction of Octavia E. Butler, mentorship is a rocky path, and every lesson comes at a price. The award-winning author of science fiction classics Parable of the Sower and Kindred bestows these compelling, long lost gems “like the miraculous discovery that the beloved book you’ve read a dozen times has an extra chapter” (Los Angeles Review of Books).

    This edition contains the original introduction by Theodore Sturgeon and the original foreword by Harlan Ellison, along with a brief update comment by Ellison that was added in the 1983 edition. Among Ellison's more famous stories, two consistently noted as among his very best ever are the title story and the volume's concluding one, Pretty Maggie Moneyeyes.Since Ellison himself strongly resists categorization of his work, we won't call them science fiction, or SF, or speculative fiction or horror or anything else except compelling reading experiences that are sui generis. They could only have been written by Harlan Ellison and they are incomparably original.CONTENTS"I Have No Mouth & I Must Scream""Big Sam Was My Friend""Eyes of Dust""World of the Myth""Lonelyache""Delusion for Dragonslayer""Pretty Maggie Moneyeyes"
