Xenocide is the third installment in the Ender series by Orson Scott Card. This book introduces some new characters too us from the planet of Path. The people of path consist of regular people and the godspoken; people who speak with the gods by performing cleansing rituals to purify themselves. All the godspoken are genious'. We also, of course, get to hear more of the story of Ender. He is now married and lives on Lusitania. Valentine is on her way with her family to help Ender and the people of Lusitania because of the fleet being sent their way with the "Little Doctor"; a device that can wipe out an entire planet completely. Faced with this, as well as the Descolada virus, Ender and those around him (or in him) must find a way to save themselves and two sentient aliens from xenocide.
