Card returns to the highly popular, award-winning story of Andrew "Ender" Wiggin, the boy wonder who saved humanity from alien invasion and, guilt-ridden over his near-total destruction of the alien species, has now become a sort of traveling conscience. This third Ender novel picks up where Speaker for the Dead left off: on the planet Lusitania, Ender and the other human colonists strive to neutralize the "descolada," a possibly sentient virus that adapts itself rapidly to every attack.
