Ender's Game
by Orson Scott Card
From New York Times bestselling author Orson Scott Card, Ender's Game—adapted to film in 2013 starring Asa Butterfield and Harrison Ford—is the classic Hugo and Nebula award-winning science fiction novel of a young boy's recruitment into the midst of an interstellar war. In order to develop a secure defense against a hostile alien race's next attack, government agencies breed child geniuses and train them as soldiers. A brilliant young boy, Andrew "Ender" Wiggin lives with his kind but distant parents, his sadistic brother Peter, and the person he loves more than anyone else, his sister Valentine. Peter and Valentine were candidates for the soldier-training program but didn't make the cut—young Ender is the Wiggin drafted to the orbiting Battle School for rigorous military training. Ender's skills make him a leader in school and respected in the Battle Room, where children play at mock battles in zero gravity. Yet growing up in an artificial community of young soldiers Ender suffers greatly from isolation, rivalry from his peers, pressure from the adult teachers, and an unsettling fear of the alien invaders. His psychological battles include loneliness, fear that he is becoming like the cruel brother he remembers, and fanning the flames of devotion to his beloved sister. Is Ender the general Earth needs? But Ender is not the only result of the genetic experiments. The war with the Buggers has been raging for a hundred years, and the quest for the perfect general has been underway for almost as long. Ender's two older siblings are every bit as unusual as he is, but in very different ways. Between the three of them lie the abilities to remake a world. If, that is, the world survives. Orson Scott Card's Ender's Game is the winner of the 1985 Nebula Award for Best Novel and the 1986 Hugo Award for Best Novel.

Book
Dragon's Egg
by Robert L. Forward
“In science fiction there is only a handful of books that stretch the mind—and this is one of them.”—Arthur C. Clarke In a moving story of sacrifice and triumph, human scientists establish a relationship with intelligent lifeforms—the cheela—living on Dragon’s Egg, a neutron star where one Earth hour is equivalent to hundreds of their years. The cheela culturally evolve from savagery to the discovery of science, and for a brief time, men are their diligent teachers. Praise for Dragon’s Egg “Bob Forward writes in the tradition of Hal Clement’s Mission of Gravity and carries it a giant step (how else?) forward.”—Isaac Asimov “Dragon’s Egg is superb. I couldn’t have written it; it required too much real physics.”—Larry Niven “This is one for the real science-fiction fan.”—Frank Herbert “Robert L. Forward tells a good story and asks a profound question. If we run into a race of creatures who live a hundred years while we live an hour, what can they say to us or we to them?”—Freeman J. Dyson “Forward has impeccable scientific credentials, and . . . big, original, speculative ideas.”—The Washington Post

Ringworld
by Larry Niven
Winner of the Hugo and Nebula Awards for best novel Four travelers come to the ringworld. . . Louis Wu: human and old; bored with having lived too fully for far too many years. Seeking a challenge, and all too capable of handling it. Nessus: a trembling coward, a puppeteer with a built-in survival pattern of nonviolence. Except that this particular puppeteer is insane. Teela Brown: human; a wide-eyed youngster with no allegiances, no experience, no abilities. And all the luck in the world. Speaker-To-Animals: kzin; large, orange-furred, and carnivorous. And one of the most savage life-forms known in the galaxy. Why did these disparate individuals come together? How could they possibly function together? And where, in the name of anything sane, were they headed?
Book
The Time Traveller's Wife
by Audrey Niffenegger
This exceptional first novel is the story of Henry and Clare, who have known each other since Clare was 6 and Henry was 36, and were married when Clare was 20 and Henry 28. This is possible only because Henry is one of the first people diagnosed with Chrono-Displacement Disorder: periodically his genetic clock resets and he flashes to other points in time, usually moments of emotional gravity for him. His disappearances are spontaneous, his experiences unpredictable, alternately harrowing and amusing. Audrey Niffenegger explores the effects this condition has on Henry and Clare's marriage and their passionate love for each other, as the story unfolds from both points of view. Clare and Henry strain to live as normal a life as they can, pursuing goals that will be familiar to most readers - steady jobs, love, good friends, children of their own. That these are all threatened by something Henry can neither prevent nor control makes this story profoundly moving and entirely unforgettable.
