Children of the Mind, fourth in the Ender series, is the conclusion of the story begun in the third book, Xenocide. The author unravels Ender's life and reweaves the threads into unexpected new patterns, including an apparent reincarnation of his threatening older brother, Peter, not to mention another "sister" Valentine. Multiple storylines entwine, as the threat of the Lusitania-bound fleet looms ever nearer. The self-aware computer, Jane, who has always been more than she seemed, faces death at human hands even as she approaches godhood. At the same time, the characters hurry to investigate the origins of the descolada virus before they lose their ability to travel instantaneously between the stars. There is plenty of action and romance to season the text's analyses of Japanese culture and the flux and ebb of civilizations. But does the author really mean to imply that Ender's wife literally bores him to death? --Brooks Peck
