'Proper galaxy-spanning space opera' Iain M. Banks on Seeds of Earth The Warcage is a feat of unprecedented stellar engineering: two hundred worlds harnessed to an artificial sun. Built to travel through space as a monument to peace between alien species, its voracious rulers have turned it into a nightmarish wasteland, capturing new planets for slaves and resources, then discarding the old. Now, when a verdant agri-world is pulled out of its orbit and a deal goes bad, it is up to the captain of a smuggling ship to journey into the Warcage and rescue his crew. Science fiction on an epic scale - Ancestral Machines is a stand-alone science fiction adventure set in Michael Cobley's bestselling Humanity's Fire universe. Perfect for fans of Iain M.
