The Sabbat War is a savage Imperial crusade, cutting a bloody, burning path across a vast swathe of the Imperium's lost territory. On the front line, the stalwart regiments of the Astra Militarum, including the valiant Tanith First-and-Only—better known as Gaunt’s Ghosts—confront the relentless menace of Chaos, the Archenemy of Mankind. There is, and ever will be, only war.

An Imperial general has defected to the enemy, and the secrets he carries could spell the end of the Sabbat Worlds Crusade. Colonel-Commissar Gaunt and a small team from the Tanith First must infiltrate an enemy-held world and gain the trust of the local underground, all the while trying desperately to avoid the ever-present taint of Chaos. Their mission: to stop the traitor general from revealing his secrets - by any means necessary.

After seven long years of conflict, the Horus Heresy nears its end. But now, as the Warmaster Horus marches on Terra to rip his father from the Throne, the seat of the arch-traitor’s power lies empty. Cthonia, a world once dominated by brutal murder-gangs, is occupied by the Emperor’s praetorians—the indomitable Imperial Fists. For the Sons of Horus, this outrage demands a reckoning. 

The End Times are coming. With the hordes of Chaos marshalling in the north, Emperor Karl Franz leads his armies in defence of his realm. But when the worst happens, Reiksmarshal Kurt Helborg must return to Altdorf, the capital of the Empire. There, he must steel himself and prepare his soldiers to defend the jewel of the Empire from the corrupted advance of the forces of Chaos. As plague spreads and the defences weaken, all seems lost—until help arrives from a most unexpected source... if Helborg can bring himself to accept it.

When the vital forge world of Orestes comes under attack by a legion of Chaos Titans, the planet is forced to appeal for help. The Titans of Legio Invicta, although fresh from combat and in desperate need of refit and repair, respond, committing their own force of war engines to the battle. As the god-machines stride to war, the world trembles, for the devastation they unleash could destroy the very world they have pledged to save.

Pursued by vengeful eldar, Magos Kotov’s Explorator armada heads into a newly revealed area of space in pursuit of ancient secrets. As the Adeptus Mechanicus forces and Black Templars Space Marines tackle the twin threats of the wrathful aliens and insurrection aboard the fleet, a greater danger reveals itself.

The Indomitus Crusade continues its war across the stars. The primarch Roboute Guilliman has finally broken through the orkish threat bedevilling the sectors near Fenris, and makes ready to push on his bid to stabilise the Imperium Sanctus—but old and bitter foes stand in his way. Kor Phaeron, the Dark Cardinal, threatens the previously stable core of the Segmentum Solar. Waves of rebellion instigated by his infiltrating priests suggest an imminent, large-scale invasion by the Word Bearers Legion. 

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.

The Officio Assassinorum safeguards the future of humanity. Its agents are the bloody-handed, secret saviours of the Imperium, killers charged with achieving the impossible...and Vindicare assassin Absolom Raithe has just been handed the most difficult assignment of his career.

Huron Blackheart is the lord of the Red Corsairs, master of the lawless Maelstrom and its piratical denizens—but oathbreakers and renegades can seldom rely on the loyalty of their followers. With the galaxy thrown into turmoil by the return of Roboute Guilliman, the former Tyrant of Badab faces a renewed Imperium and fresh challengers emerging within his own ranks. Huron must call on every trick he knows to stay in control—and alive. 

The Great Crusade is ending. The Emperor has returned to Terra, while Horus remains among the stars to complete the unification of humanity. As the Imperial armies fight the final battles of the age, Remembrancer Solomon Voss seeks the answer to one question—why does Sigismund, First Captain of the Imperial Fists and greatest champion of the Legions, believe that war will not end? Granted a rare audience with the master of the Templars, the answer takes Voss on a revelatory journey to a time before Sigismund became a Space Marine.

Saint Sabbat has brought a miracle to the war-torn city of Ghereppan, but one battle is not the war. The voice of Magister Sek still haunts the Imperial forces, defying their victory, mocking their faith. Between the trickery of the Archenemy and the mercurial visions of the Saint, the Space Marines of Damocles Squad must find the truth: is this their one chance for a final victory on Urdesh, or is it a trap that could destroy them all?

Urdesh is a brutal world, the fires of its forge-cities mixing with the many volcanoes and an endless expanse of battle wreckage littering the plains. When the reincarnation of Saint Sabbat herself appears on the blasted battlefields of Urdesh, powerful forces race to secure that which may decide the ultimate fate of the world, and the crusade at large. 

The grand halls of Fenris grow ever quieter in the wake of the Space Wolves' arduous campaigns. Concerned by his Chapter’s diminishing numbers, the Great Wolf Logan Grimnar entrusts Njal Stormcaller with a task - to find a remedy for their plight. When a 10,000-year-old enemy embeds itself in the Rune Priest’s mind, it claims that the salvation he seeks lies where an ancient enmity began - on Prospero, the ruined home world of the Thousand Sons Legion. 

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.
