They enslaved humanity three thousand years ago. Tall, strong, perfect, superhuman and near immortal they rule from their glittering palaces in the eternal city in the centre of the world. They are called Those Above by their subjects. They enforce their will with fire and sword. Twenty five years ago mankind mustered an army and rose up against them, only to be slaughtered in a terrible battle. Hope died that day, but hatred survived. Whispers of another revolt are beginning to stir in the hearts of the oppressed: a woman, widowed in the war, who has dedicated her life to revenge; the general, the only man to ever defeat one of Those Above in single combat, summoned forth to raise a new legion; and a boy killer who rises from the gutter to lead an uprising in the capital.

For centuries beyond counting, humanity has served the Others, god-like Eternals who rule from their cloud-capped mountain-city, building a civilization of unimagined beauty and unchecked viciousness. But all that is about to change. Bas Alyates, grizzled general of a thousand battles, has assembled a vast army with which to contend with the might of Those Above. Eudokia, Machiavellian matriarch and the power behind the Empty Throne, travels to the Roost, nominally to play peacemaker - but in fact to inspire the human population toward revolt. Deep in the dark byways of the mountain's lower tiers, the urchin Pyre leads a band of fanatical revolutionaries in acts of terrorism against their inhuman oppressors. Against them, Calla, handmaiden of the Eternals' king, fights desperately to stave off the rising tide of violence which threatens to destroy her beloved city. The story that begun in Those Above comes to a conclusion in this battle for the hearts and minds of the human race in Those Below.
