Valorous Heart. Our Martyred Lady. Bloody Rose. These names of Adepta Sororitas orders are famed across the galaxy, as are the Battle Sisters who serve the emperor's will. To die in the name of the God-Emperor of Mankind is to live eternal, and none are more willing to bleed in his name than the Adepta Sororitas - the Sisters of Battle. The Book of Martyrs charts the deaths of these exemplars.

During the turbulent Reign of Blood, a great schism in the Imperial Ecclesiarchy threatened all of Terra and promised a darkness to rival the terrors of Old Night. Fell times have come again to the Imperium, and a War of Faith appears inevitable. Standing in the way of catastrophe is Celestine, the Living Saint and one of the greatest heroes of the age. Only she can reunite the warring factions of the Ecclesiarchy and prevent a second Reign of Blood.

With the birth of the Cicatrix Maledictum the Imperium of Mankind suffers as never before. Conflict and corruption is rife on every front and precious little hope remains, save for those who hold to their faith when faced with destruction.... Denied a martyr’s death during the battle for Ophelia VII, Sister Evangeline of the Order of Our Martyred Lady is blessed with a new and grave duty: to embark on a pilgrimage beyond the Great Rift to recover a precious and powerful artefact - the Shield of Saint Katherine.

Opal is a gleaming shrine world of saints and soldiers, beloved of the Emperor Himself.

But all is not well – despite what its planetary leaders would have Augusta believe, political danger bubbles under the surface, and rebel attacks gnaw away at the city’s outskirts. The greatest threat, however, is yet to come.

In the grim nightmare future of the 41st millennium, the witch-hunting zealots of the the Sisters of Battle stand between humanity and damnation.

Following Vaun's trail to the planet Neva, Miriya takes her sisters in pursuit and, along with Hospitalier Sister Verity, starts her investigations.

The Blood Angels Chapter of Space Marines is under threat. Having obliterated all human life in the Red Scar region of space, the largest tendril of Hivefleet Leviathan ever seen in the Imperium has converged and is making relentlessly for Baal. To face this awesome foe, Commander Dante has called upon the Successor Chapters of the ancient Ninth Legion. The Sons of Sanguinius gather in numbers not seen since the dark days of the Horus Heresy.

Inquisitor Greyfax and a retinue of incorruptible Grey Knights are sent on a mission by the reborn Primarch Guilliman to recover the Eye of Night, a fabled artefact of Ruin that could weaken the Great Rift. It will be no easy task as Greyfax – with the aid of a long dead inquisitor – must journey into the Eye of Terror itself and challenge a traitor of a truly ancient pedigree, the crone Moriana.

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.

The Sisters of Battle are the Emperor's most devout worshippers, fierce warriors preaching the purity of the Imperium and scourging their enemies with bolter and flamer. On a distant world, the Ecclesiarchy outpost of Sanctuary 101 was wiped out by an implacable foe - the fearless, soulless necrons. Now, a mission of the Sisterhood has returned to reconsecrate the site - but the metallic nightmares still lurk in the darkness, guarding a secret that has lain dormant for millennia.

When a mysterious messenger contacts the Adepta Sororitas, Celestian Miriya must travel to Hollos and pass judgment on the world. Will she find a world embracing the Emperor's truth or one in need of cleansing? Her decision will liberate or condemn an entire planet.

The scattered worlds of the Elara's Veil nebula were once protected by the oath of unity sworn by three mighty Chapters of the Adeptus Astartes. The Star Scorpions were undone by flaws in their genetic coding. The Celestial Lions were ravaged by the Inquisition for sins they did not commit. Now, after hundreds of years, only the Emperor's Spears still keep their vigil. They are barbarian watchmen against the Outer Dark, bloodied but unbroken in their long duty.

Fell times have come to the galaxy. Cadia has fallen, destroyed by the onslaught of Chaos. A Great Rift in the warp has opened, and from its depths spew daemons and the horrors of Old Night. But all hope is not lost… A hero, long absent, has returned, and with him comes the wrath of the Ultramarines reborn. Roboute Guilliman has arisen to lead the Imperium out of darkness on a crusade the likes of which has not been seen since the fabled days of the Emperor. But never before have the forces of Ruin amassed in such numbers, and nowhere is safe from despoliation.

The shrine world of Divinatus Prime has become lost to the light of the Astronomican, and no ship can piece its veil. Only the Lord of Death himself, Blood Angels Chief Librarian Mephiston, has any hope of discerning the fate of this once pious world. After enacting a powerful blood ritual, Mephiston and an honour guard of his fellow Blood Angels reach the stricken shrine world to find it seized by religious civil war. Each faction fights for dominance of a potent artefact, the Blade Petrific, said to be wrought by the Emperor Himself.

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.

For Ianthe, war is all too familiar. A former soldier in the Astra Militarum, she now serves Inquisitor Covenant as an agent of the Throne.

Throughout the tortured galaxy, Ephrael Stern is known by many names. The Thrice-born. The Daemonifuge. The Heretic Saint. Trapped deep within Imperium Nihilus following the coming of the Great Rift, the maligned Sister of Battle fears the Imperium is no more. The God-Emperor’s light, which has guided her through centuries of strife, has too extinguished. Seemingly forsaken, Stern is bereft until a mysterious stranger arrives, offering her a new destiny. One that might yet see the Imperium saved. Stern must prove herself worthy of the God-Emperor’s grace once more.

Sister Adamanthea is an oddity among the Adepta Sororitas - a Sister Repentia who has been cleansed of her sin and returned to her duty, rather than finding penance in death. Seen by the faithful as a living miracle, she herself is unsure. Still feeling the weight of her crime, she wonders if she belongs in the sisterhood at all. When she is forced to appear with a famed priest on a most holy day, Adamanthea's doubts itensify...until disaster strikes.

Since the halcyon days of the Great Crusade, these noble rogue trader dynasties have plied the void in the Emperor’s name, answering to whomsoever sits as the king of the Davamir Compact. There has been profit and adventure and abundance in these times… Yet now the galaxy is changed, divided by the birth of the Great Rift. As plans are drawn up for the most immense crusade imaginable, the Emperor’s reborn son demands that the Compact seek a way across the Rift.
