“Fascinating . . . memorable . . . revealing . . . perhaps the best of Carl Sagan’s books.”—The Washington Post Book World (front page review) In Cosmos, the late astronomer Carl Sagan cast his gaze over the magnificent mystery of the Universe and made it accessible to millions of people around the world. Now in this stunning sequel, Carl Sagan completes his revolutionary journey through space and time. Future generations will look back on our epoch as the time when the human race finally broke into a radically new frontier—space. In Pale Blue Dot, Sagan traces the spellbinding history of our launch into the cosmos and assesses the future that looms before us as we move out into our own solar system and on to distant galaxies beyond. The exploration and eventual settlement of other worlds is neither a fantasy nor luxury, insists Sagan, but rather a necessary condition for the survival of the human race. “Takes readers far beyond Cosmos . . . Sagan sees humanity’s future in the stars.”—Chicago Tribune

The classic postapocalyptic thriller with “all the reality of a vividly realized nightmare” (The Times, London). Triffids are odd, interesting little plants that grow in everyone’s garden. Triffids are no more than mere curiosities—until an event occurs that alters human life forever. What seems to be a spectacular meteor shower turns into a bizarre, green inferno that blinds everyone and renders humankind helpless. What follows is even stranger: spores from the inferno cause the triffids to suddenly take on a life of their own. They become large, crawling vegetation, with the ability to uproot and roam about the country, attacking humans and inflicting pain and agony. William Masen somehow managed to escape being blinded in the inferno, and now after leaving the hospital, he is one of the few survivors who can see. And he may be the only one who can save his species from chaos and eventual extinction . . . With more than a million copies sold, The Day of the Triffids is a landmark of speculative fiction, and “an outstanding and entertaining novel” (Library Journal). “A thoroughly English apocalypse, it rivals H. G. Wells in conveying how the everyday invaded by the alien would feel. No wonder Stephen King admires Wyndham so much.” —Ramsey Campbell, author of The Overnight “One of my all-time favorite novels. It’s absolutely convincing, full of little telling details, and that sweet, warm sensation of horror and mystery.” —Joe R. Lansdale, author of Edge of Dark Water
