Of the various star systems that make up the Confederation, most lie thousands of light-years from First Earth-and out here, no one is free. The agencies that govern the Confederation are as corrupt as the crime bosses who patrol it, and power is held by anyone with enough greed and ruthlessness to claim it. That power is derived from one thing: metatech, the devices that allow people to travel great distances faster than the speed of light. Jeth Seagrave and his crew of teenage mercenaries have survived in this world by stealing unsecured metatech, and they’re damn good at it. Jeth doesn’t care about the politics or the law; all he cares about is earning enough money to buy back his parents’ ship, Avalon, from his crime-boss employer and getting himself and his sister, Lizzie, the heck out of Dodge. But when Jeth finds himself in possession of information that both the crime bosses and the government are willing to kill for, he is going to have to ask himself how far he’ll go to get the freedom he’s wanted for so long.

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.
