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.

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?

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.

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. 

Saint Sabbat has returned, and she is being hunted by the deadliest of assassins. Gaunt's Ghosts must fight to protect her - but can they defend against treachery from within? It's the culmination of a massive story arc that sees tragedy strike even as the Sabbat Worlds Crusade is given new hope with the reappearance of the Saint herself. Mysticism and warfare collide, with compelling results.

As the Tyrannic Wars sweep across the face of the Eastern Fringe, Cain and Jurgen find themselves on the jungle moon of a gas giant, fighting off a splinter fleet. The world is uninhabited, but must be protected to prevent the tyranid advance threatening several nearby systems. The situation goes from bad to worse when Cain and the Catachans run into a force of insidious xenos, and the two factions are thrown into a temporary alliance purely to survive.

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.

Commissar Ciaphas Cain is a renowned and revered hero of the Imperium, a man who has faced and survived some of the vilest creatures the universe can throw at him. But when he is sent to a river-world, he must deal with a dangerous enemy, an enemy whose true identity remains unknown. As his vessel traverses the straits of the planet, Cain must uncover the face of this new foe so that he can understand and escape it. Caught in the enemy crossfire, the commissar has no place to run and his nerve will be tested to the very limits.

Volpone Glory covers the exploits of the soldiers of the 50th Volpone of the Royal Volpone Regiment. Their ranks are filled with proud and arrogant soldiers who come from the noble families of Volpone, earning them the name 'Bluebloods' among the Astra Militarum. Nick Kyme breathes life and humility into the members of this otherwise supercilious regiment as they battle against impossible odds.

Exile to the miserable world of Sedh, the disgraced Necron Lord Oltyx is consumed with bitterness. Once heir to the throne of a dynasty, he now commands nothing but a dwindling garrison of warriors, in a never-ending struggle against Ork invaders. Oltyx can think of nothing but the prospect of vengeance against his betrayers, and the reclamation of his birthright. But the Orks are merely the harbingers of a truly unstoppable force. Unless Oltyx acts to save his dynasty, revenge will win him only ashes. 

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 paths of Roboute Guilliman and his fallen brother Mortarion bring them inexorably together on Iax. Once a jewel of the Imperium, the garden world is dying as the plans of the Lord of Death to use it as a fulcrum to drag the stellar realm of Ultramar into the warp come to deadly fruition. While Guilliman attempts to prevent the destruction of his kingdom, Mortarion schemes to bring his brother low with the Godblight, a disease created in the Cauldron of Nurgle itself, made with the power to destroy a son of the Emperor. 

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 Monthax, Colonel-Commissar Ibram Gaunt and his Tanith First-and-Only await the order to advance into the sweltering jungle and drive the alien eldar from the world. As battle approaches, Gaunt walks the lines, raising his men's spirits and remembering their most heroic deeds - and the tragedies that have dogged Gaunt's Ghosts from the day of their founding on lost Tanith. The day that Gaunt became known as the Ghostmaker. 

Gaunt’s Ghosts embark on their most dangerous mission yet as they make a daring drop assault on the world of Phantine. With the elite enemy Blood Pact and vicious xenos mercenaries ranged against them and short of ammunition with no means of escape, things look grim for the Tanith First. But the greatest danger may come from within the regiment as an old grudge is settled and tragedy strikes.
