Galactic North (Revelation Space)

In a triumphant return to the Revelation Space universe, the author declared by SFX to be “one of SF’s best and most ambitious novelists” offers his first collection. With eight short stories and novellas—including three never before seen— Galactic North imparts the centuries-spanning events that have produced this dark and turbulent world…
 
Centuries from now, solidarity stretches thin as humanity spreads past the solar system and to the nearest stars. Technology has produced powerful new tools—but lethal risk will always accompany great advancement.
 
And without foresight, opposing groups may fracture multiple worlds. Between the Demarchists and the Conjoiners, the basic right to expand human intelligence—beyond its natural limits—has become a war-worthy cause. Only vast lighthugger starships bind these squabbling colonies together, manned by the panicky and paranoid Ultras. And the hyperpigs just try to keep their heads down.
 
The rich get richer. And everyone tries not to think about the worrying number of extinct alien civilizations turning up on the outer reaches of settled space…because who’s to say that humanity won’t be next?
