Xenocide is the third installment of the Ender series. On Lusitania, Ender found a world where humans and pequeninos and the Hive Queen could all live together; where three very different intelligent species could find common ground at last. Or so he thought. But Lusitania also harbors the descolada, a virus which kills all humans it infects, but which the pequeninos require in order to transform into adults.

In the aftermath of his terrible war, Ender Wiggin disappeared, and a powerful voice arose: the Speaker for the Dead, who told the true story of the Bugger War. Now, long years later, a second alien race has been discovered by Portuguese colonists on the planet Lusitania. But again the aliens' ways are strange and frightening...again, humans die. And it is only the Speaker for the Dead, who is also Ender Wiggin the Xenocide, who has the courage to confront the mystery...and the truth.

Andrew "Ender" Wiggin was not the only child in the Battle School; he was just the best of the best. In this book, Card tells the story of another of those precocious generals, the one they called Bean, the one who became Ender's right hand, part of his team, in the final battle against the Buggers. Bean's past was a battle just to survive. His success brought him to the attention of the Battle School's recruiters.

Nearly 100 years before the events of Orson Scott Card’s best-selling novel Ender’s Game, humans were just beginning to step off Earth and out into the Solar System. A thin web of ships in both asteroid belts; a few stations; a corporate settlement on Luna. No one had seen any sign of other space-faring races; everyone expected that First Contact, if it came, would happen in the future, in the empty reaches between the stars. Then a young navigator on a distant mining ship saw something moving too fast, heading directly for our sun.

Best selling SF author Orson Scott Card brings to life a new chapter in the saga of Ender's Earth.

Earth and its society have been changed irrevocably in the aftermath of Ender Wiggin's victory over the Formics. The unity forced upon the warring nations by an alien enemy has shattered. Nations are rising again, seeking territory and influence, and most of all, seeking to control the skills and loyalty of the children from the Battle School.
