Voices of the Dead is the direct result of the strategy Ender. Ender and his sister Valentine paced the universe for thousands of years after Ender has exterminated the Doryphores. They wrote a manifesto for two appreciation of this alien race once hated, and led behind a crowd following called "Spokesman of the Dead", a kind of itinerant priests whose role is to establish the truth on the life of a dead man recently. And now humanity discovers an intelligent alien race news: Pequeninos, a sort of beings half man half-pig, living in the forests of the planet Lusitania. Ender receives the call of an inhabitant of Lusitania, who asked him to come and talk to the death of one of his relatives. This trip will take him to moral dilemmas whose scale will reach that of its untangled with Doryphores. All humanity wants to preserve the lives of Pequeninos, but that does not hide he will let them vegetate in their primitive and tribal civilization?
A sequel to clear the height of the first volume, but in a rather different vein. Card is again measured and very subtle in its treatment of racism and xenophobia. The coexistence of different cultures here is the heart of the novel, and the author is doing very well. I do not think I saw one addressing these issues of comparable quality elsewhere in science fiction. Card also describes very convincingly close family relations and that is a real treat for the reader. So clearly a recommendation, but read the first book before preference.
