For thousands of years, there has been a cycle: a Demon King rises and conquers, and a Hero is reborn a hundred years later to defeat him. Each time, civilizations are ground to dust beneath the Demon King's hordes, but humanity has remained secure in the belief that a Hero of legend will always save them. There's just one slight problem. It's only been 23 years since the Demon King's latest rise, and this time, he's already conquered more than half the world. If humanity simply waits for the Hero's return, there may be no world left for him to save.

This second volume of Orson Scott Card's five-volume anthology of short stories features seven tales exploring possible future scenarios for the human race. A fascistic government's capital punishment extends beyond death. Intellectually superior aliens from a doomed world choose Earth's dogs as their new vessels. Not-quite-human beings on an Earth wasted by biological warfare continously fight an enemy which has long been annihilated.
