Book III of Revelation Space. Humanity has endured centuries of horrific plague and a brutal interstellar war. It’s time for a few decades of peace and quiet. No such luck – there’s a new threat. Stirred from aeons of sleep, the Inhibitors – ancient alien killing machines designed to eliminate any emergent intelligence –  have targeted mankind. Fleeing the first wave of machines, a ragtag group of refugees headed by war veteran Clavain waits for the next phase of the cull. But with Clavain sunk deep in despondency, the leadership falls to Scorpio, the product of a flawed experiment in genetic engineering who has every reason to hate humanity. Then their little colony receives an unexpected visitor: an avenging angel, a girl born in ice, gifted with the power to lead humanity to safety and the ability to draw down mankind’s darkest enemy. On Hela, where vast travelling cathedrals circle the world in endless processions, the witnessing of a miraculous event has created an apocalyptic new religion. And as the cathedrals crawl closer to to the treacherous fissure known as Absolution Gap, a dark and unsettling truth becomes apparent: to beat one enemy, it may be necessary to forge an alliance with something much, much worse…Cover art by Chris Moore.
