Warhammer 40,000 novel by Guy Haley
Black Library hardback edition
Belisarius Cawl takes on necrons — and Vashtorr the Arkifane
Read moreRead less
The Imperium's greatest mind has a plan — and it's typically audacious. Belisarius Cawl intends to stabilise the Attilan Gap and open a safe passage through the Great Rift to Imperium Nihilus, where Roboute Guilliman is cut off on the far side. Guy Haley, the safe pair of hands behind so much of the modern 40K narrative, gives the ancient archmagos a story worthy of his ten-thousand-year ego.
The story
To finish his great work, Cawl needs control codes held on a necron tomb world trapped on the event horizon of a black hole
He recruits help from across the Adeptus Mechanicus — even he can't do this alone
But his tinkering has drawn the gaze of something far worse than ancient xenos: Vashtorr the Arkifane
Why read it
Cawl is one of the most consequential figures in the 41st Millennium, and this is his defining outing
Necrons, the Adeptus Mechanicus and the forces of Chaos colliding over a galaxy-changing prize
Written by Guy Haley, author of the Dark Imperium series
Big, clever, consequential 40K fiction — the kind of book that shifts the setting rather than just visiting it.
