On the ice world of Simia Orichalcae a spate of mysterious disappearances is causing unrest amongst the mine workers, and, as senior officer of the Astra Militarum, Commissar Ciaphas Cain is nominated to investigate. Unbeknownst to him, the planet is right in the path of a major ork incursion, and, as the savage greenskins attack, a malevolent evil begins to stir deep in the ice caves. 

Ciaphas Cain's latest mission takes him and his Valhallan regiment to the planet of Adumbria to defend against an approaching Chaos invasion. However, infighting with fellow Imperial Guard regiments from the world of Tallarn, commanded by an old 'friend' of Cain's from the Schola Progenium and the uprising of a sinister cult on the planet puts paid to any hopes of an easy life.

Once again, reluctant hero Commissar Cain is catapulted into glory in the fourth instalment of this tremendously popular series. Escaping from a disastrous space battle, the commissar and his malodorous sidekick Jurgen crash-land behind enemy lines. Even the sly Cain can't avoid a straight fight this time, as the only way out is to round up what few troops they can find and fight their way back to safety. Unfortunately, hundreds of thousands of barbaric alien orks stand in their way.

On Periremunda, the populace are rioting. With local forces unable to contain the widespread civil disorder, Commissar Cain and his regiment of Valhallans are called in to help. However, it seems there is more to the rebellion than first appeared, and Cain suspects sinister forces at work behind the scenes. When the commissar is reunited with Inquisitor Amberley Vail, it seems his fears are realised. In this the fifth book in the popular Ciaphas Cain series, our hero is thrown into a deadly conspiracy that even he might not be able to emerge from alive.

After a long and distinguished career defending the Imperium from its many enemies, Commissar Cain is enjoying a well-deserved retirement on Perlia, teaching in a schola progenium. But when a Black Crusade threatens the sector, all able-bodied citizens must rise to the defence, including Cain and his cadets. As the forces of Chaos overwhelm Perlia, can the wily commissar prove himself to be a real hero of the Imperium one last time?

Imperial commissar Ciaphas Cain returns to Nusquam Fundumentibus to crush the ork attacks which have been plaguing the frozen planet. But when his ship crashes into the wastelands outside the capital it disturbs a far greater enemy, one which has lain dormant under the permafrost since long before the Imperium came to this world and could now threaten the whole sector.

The Death Korps of Krieg are deployed to a soul-crushing siege in the Octarius War Zone. They’re the right regiment for the job, though victory might come at a price that some might balk to pay.

For a thousand years, the Sabbat Worlds have been lost to the Imperium, claimed by the dread powers of Chaos. Now, a mighty crusade seeks to return the sector to Imperial rule. And at the forefront of that crusade are Colonel-Commissar Ibram Gaunt and the Tanith First and Only - better known as Gaunt’s Ghosts. Trapped in the grinding trench warfare of Fortis Binary, the Ghosts find themselves drawn into a conspiracy to assassinate the crusade’s leader, Warmaster Macaroth.

The Inquisition moves amongst mankind like an avenging shadow, striking down the enemies of humanity with uncompromising ruthlessness. When he finally corners an old foe, Inquisitor Gregor Eisenhorn is drawn into a sinister conspiracy. As events unfold and he gathers allies - and enemies - Eisenhorn faces a vast interstellar cabal and the dark power of daemons, all racing to recover an arcane text of abominable power: an ancient tome known as the Necroteuch.

A century after his recovery of the alien Necroteuch, Gregor Eisenhorn is one of the Imperial Inquisition's most celebrated agents. But when a face from his past returns to haunt him, and he is implicated in a great tragedy that devastates the world of Thracian Primaris, Eisenhorn's universe crumbles around him. The daemon Cherubael is back, and seeks to bring the inquisitor to ruin - either by his death, or by turning him to the service of the Dark Gods.    

It's the end of Gaunt's Ghosts! No, really, the Tanith First has been disbanded, and Gaunt has been sent elsewhere. What will it take to draw them back together? How about a stonking big Chaos attack? The Tanith First are no more. Moved into another regiment under a charismatic new commander, the loyalties of the former Ghosts are put to the test when Colonel-Commissar Gaunt, long believed dead, returns. As the enemy overrun the Imperial forces, Gaunt must fight not only to be reunited with his Ghosts, but to stop all their lives being thrown away in an unwinnable war.

In the hellish sprawl of Imperial Terra, Ordo Hereticus Inquisitor Erasmus Crowl serves as a stalwart protector, for even the Throneworld is not immune to the predations of its enemies. In the course of his duty, Crowl becomes embroiled in a dark conspiracy, one that leads all the way to the halls of the Imperial Palace. As he plunges deeper into the shadowy underbelly of the many palace districts, his investigation attracts the attention of hidden forces, and soon he and his acolyte Spinoza are being hunted.

Hunted by his former allies as a radical and enemy of the Imperium, Inquisitor Gregor Eisenhorn must fight to prove that he remains loyal as he tracks down a dangerous heretic whom the Inquisition believes dead, the dread former Inquisitor Quixos. As he grows more desperate for victory, Eisenhorn uses ever darker means to achieve his goals, but how far can he go using the weapons of the enemy until he becomes that very enemy, and no different to the traitor he hunts?

Before the being called the Emperor revealed himself, before the rise of the aeldari, before the necrontyr traded their flesh for immortal metal, the world was born in violence. Even when they inhabited bodies of flesh, Trazyn the Infinite and Orikan the Diviner were polar opposites. Trazyn, a collector of historical oddities, presides over a gallery full of the most dangerous artefacts - and people - of the galactic past. Orikan, a chronomancer without peer, draws zodiacs that predict and manipulate the future. 

On the battlefields of Aexe Cardinal, the stalwart forces of the Imperial Guard are locked in a deadly stalemate with the dark armies of Chaos. Colonel-Commissar Ibram Gaunt and his regiment, the Tanith First and Only, are thrown headlong into the living hell of trench warfare, where death by an unseen enemy is always just a moment away. The only chance for Gaunt and his lightly armed scouts to survive is to volunteer for a mission so dangerous that no one else dares accept it.
