The Horus Heresy is an ongoing series of science fiction novels, the first of which was published by the Black Library in 2006. The stories are set during the Horus Heresy, a galaxy-spanning civil war occurring 10,000 years prior to the setting of Games Workshop's Warhammer 40,000 tabletop miniatures wargame, and a major contributing factor to the dystopic setting of the game.

== == Most novels have been published in several countries, and in multiple media: in print, as ebooks, and as either abridged or unabridged audiobooks (in disc- or downloadable media). Additionally, there have been a number of special editions, bundles, web exclusives, and collector editions, (see below), which have been published in a variety of media, including hardcover print format. The books' cover art has been separately released in poster format.

== == The regular-edition series includes both full-length novels and short story compilations; special editions have included novellas. As is the case with other Black Library series, novels, and compilations, all the books in this series include one of several "stock" unsigned single-page preambles that provide a very general background to the stories that follow. In addition, each full-length novel includes a listing of major characters in its front matter.

The series begins with a scene-setting novel trilogy describing the start of the conflict, with a focus on the eponymous Warmaster Horus, the principal antagonist. There are also later mini story arcs within the series, and some of the short stories included in the compilations are prequels or sequels of some of the novels.

Following the opening trilogy, the novelization is not strictly sequential and the story of the Heresy may be presented in a non-linear fashion from book to book; the stories may concern events that happen earlier than their position in the series would suggest, or may include time periods already covered in other books of the series. The revisited time periods may pertain to either original events or already-covered events viewed from a different perspective. In addition, there are gaps in the narrative published so far, presumably to be filled in as the series continues; as of January 2012 the books had only covered background and early stages in the Heresy timeline.

1. Horus Rising: The seeds of heresy are sown

Horus Rising details the rise to power of Horus Lupercal, Primarch of the Luna Wolves, after the Emperor appoints him Warmaster, overall commander of the Imperial military and in charge of the Great Crusade. Much of the focus is on the Captain of the Luna Wolves' Tenth Company, Garviel Loken, as he becomes a member of the Mournival (an advisory body to Horus), and his involvement in campaigns against traitors and aliens at the close of the Great Crusade.

2. False Gods: The heresy takes root

"False Gods" redirects here. For the Abrahamic doctrine, see False god.

False Gods describes Horus' fall. In a complicated conspiracy implemented by Chaos allies, Horus is wounded on the moon of the planet Davin by an alien, Chaos-tainted weapon. In a desperate effort by his lieutenants to see him healed, Horus is taken to a temple on Davin. However the temple is secretly in service to Chaos and both Horus' wound and its supposed healing makes him susceptible to Chaos' influence. He ultimately turns against his "father", the Emperor. The events of False Gods describe the point at which Horus sets in motion the entire Heresy, an event that will change the galaxy forever.

3. Galaxy in Flames: The heresy revealed

Galaxy in Flames concerns the virus-bombing of Isstvan III and Warmaster Horus' ultimate falling into madness, which resulted in a galaxy where brother would fight brother. In a virus-choked wasteland of death and destruction, Loyalist elements of the Luna Wolves, World Eaters, Emperor's Children and Death Guard Legions fight against the traitors in a desperate show of defiance, as the first open move of the Heresy is played out.

4. Flight of the Eisenstein: The heresy unfolds

Flight of the Eisenstein follows the Eisenstein, a frigate of the Death Guard Legion commanded by Battle-Captain Nathaniel Garro of the 7th Company, one of the few commanders in the Traitor Legions that remained loyal to the Emperor. The story is about Eisenstein's escape from Isstvan III (see Galaxy in Flames above) and its voyage across the galaxy in an attempt to reach and warn the Emperor of Mankind on Holy Terra.

5. Fulgrim: Visions of treachery

Fulgrim centers around the Primarch of the Emperor's Children Legion, as he and his Legion fell into corruption and eventually became the Chosen of Slaanesh, one of the Chaos Gods. Primarch Ferrus Manus and his Iron Hands also play a prominent role in the novel, and the pivotal Battle of Isstvan V (the so-called Dropsite Massacre) is described in passing.

6. Descent of Angels: Loyalty and honour

Descent of Angels is told from the point of view of planet Caliban native Zahariel El'Zurias, who begins the novel as an Aspirant of the Order (an organization of techno-barbarian knights). The first half of the novel is set on Caliban and covers the final battles of the Order under Lion El'Jonson, the future Primarch of the Dark Angels Space Marine Legion. The book's second half describes Caliban's re-unification with the Imperium of Man as well as the actions of the Dark Angels Legion during the early years of the Great Crusade. Zahariel, selected as candidate Space Marine, is accepted as a neophyte for the Dark Angels. A future schism within the Legion is intimated in this section of the book.

7. Legion: Secrets and lies

Legion features the Alpha Legion, the 20th (and last to be formed) Space Marine Legion, known as the most secretive and inscrutable of all the Legions. It also features the Imperial Army, and a mysterious interspecies organization called the Cabal. The book describes the events that eventually lead to the decision of Alpharius-Omegon, the Legion's Primarch, to support Horus.

8. Battle for the Abyss: My brother, my enemy

Battle for the Abyss describes the lead-up to the Battle of Calth, fought between Primarch Guilliman's Ultramarines and the Word Bearers Legion. The Word Bearers plan to use an immense warship, the Furious Abyss, to spearhead their attack. The protagonists must pursue the ship and prevent it from reaching Macragge, Ultramar's capital world. If the Ultramarines break and give way to the traitorous Word Bearers, Guilliman's Legion will suffer a blow they may never recover from.

9. Mechanicum: War comes to Mars

Mechanicum is about the civil war on Mars as Traitor and Loyalist forces fight to determine which side in the struggle will receive the support of the Adeptus Mechanicus. Horus obtains the secret allegiance of highly placed Mechanicum Adepts who plot and eventually carry out a coup in order to eliminate those on Mars who are loyal to the Emperor.

10. Tales of Heresy

Tales of Heresy is a collection of short stories set mostly during the Horus Heresy, but also including stories from other periods in the Warhammer 40,000 universe. The collection provides a wider background to the Heresy, the Great Crusade, and the Imperium of Man. Compiled and edited by Nick Kyme and Lindsey Priestley.

11. Fallen Angels: Deceit and betrayal

Fallen Angels continues the Dark Angels story begun in Descent of Angels. The book tells two stories: one of Primarch Lion'El Johnson and a small group of Dark Angels as they try to deny a forge world in the Isstvan system to Horus' forces; the other of Luther (Lion'El Johnson's second), Zahariel (by now a full Space Marine), and a Dark Angels contingent sent back to Caliban as they fight against a growing insurgency that seeks to free the planet from under the Imperium's thumb.

12. A Thousand Sons: All is dust...

A Thousand Sons is the story of Primarch Magnus the Red and the Thousand Sons Legion of Space Marines, and for the most part takes place before the Heresy starts. Following a reprimand by the Emperor of Mankind for dabbling in sorcerous arts, Magnus and his Legion secretly continue to study sorcery despite being forbidden to do so. Magnus learns through sorcery of his brother Horus' impending betrayal, and tries, again through sorcery, to warn the Emperor hoping the news would justify his disobedience. However, Magnus overreaches with his powers and causes damage to a vital and secret project the Emperor was undertaking, endangering the safety of Terra itself in the process. The Emperor is enraged and orders Primarch Leman Russ and his Space Wolves Legion, accompanied by other Imperial forces, to bring Magnus and his Legion to Terra to account for themselves.

13. Nemesis: War within the shadows

Nemesis is set about two years after the events on Isstvan V described in Book 5, Fulgrim. It deals with a plan by a secret Imperial organization, the Officio Assassinorum, to eliminate Horus using an Execution Force drawn from all the "clades" (specialist assassin schools) that make up the Officio. There have been several previous unsuccessful attempts against Horus' life, and this gives a high-ranking officer of the Traitor Word Bearers Legion the idea to field a nemesis weapon of his own (a highly specialized assassin) in an audacious scheme to kill the Emperor.

14. The First Heretic: Fall to Chaos

The First Heretic details the fall to Chaos of Primarch Lorgar and his Word Bearers, the 17th Astartes Legion. The story is told largely from the point of view of Argel Tal, a Captain of the Word Bearers, and spans about 50 years, starting 43 years before the events on Isstvan V and leading up to the time when the Word Bearers are on their way to assault Calth, as related in Book 8. Following the humiliating censure of Lorgar and the 17th Legion by the Emperor himself for introducing religious worship, Lorgar is swayed by two of his most trusted lieutenants, who were already in secret allegiance with Chaos. Eventually both Primarch and Legion abandon the Imperium, and in full accord with Horus, take part in the Isstvan V battle.

15. Prospero Burns: The Wolves unleashed

Prospero Burns is part of the story arc of Book 12, A Thousand Sons. However it begins more than a century before the Space Wolves-led assault on Prospero. It is told from the point of view of Kasper Hawser, formerly a noted Terran academic, who becomes the Oral Historian (Skjald) of the 3rd Company of the Space Wolves Legion. On the surface it is his story; however the important subplot concerns the long-term machinations of Chaos to destroy both the Space Wolves and the Thousand Sons by pitting one against the other. The book also gives some important background on Warmaster Horus's fall to Chaos, thus providing a more coherent view of the Heresy and of its planning by the Chaos forces.

16. Age of Darkness

Age of Darkness is a compilation of stories providing background information on the Horus Heresy. These cover the seven-year period between the Dropsite Massacre on Isstvan V (Book 5) and the start of the campaign against Terra by the Traitor forces. "The age of knowledge and enlightenment has ended. The Age of Darkness has begun."

17. The Outcast Dead: The truth lies within

This is the first story in the series to take place entirely on Terra. It covers a relatively short period, from shortly before the Dropsite Massacre at Isstvan V (Book 5), to shortly after Primarch Magnus' catastrophic visit at the Imperial Palace (Book 12), an event that is central to the story. The main character is Kai Zulane, previously a gifted astropath attached to the Ultramarine voidship Argo. He unwittingly becomes the keeper of a secret that could decide the victor in the developing galactic civil war. The Outcast Dead are a small, disparate group of Space Marines suspected as traitors, with whom Zulane falls in during the second half of the story. In the end, the secret kept by Zulane is revealed to the one person it is actually intended for, and provides an explanation for the post-Heresy stagnation of the Imperium of Man.

18. Deliverance Lost: Ghosts of Terra

This book is mainly concerned with the actions of Primarch Corvus Corax and his command, the 19th Space Marines Legion (known as the Raven Guard), during the year following the Dropsite Massacre (Book 5). However, operatives and the Primarch of the Alpha Legion (Book 7) play a prominent role. The novel also provides some information about the developing strategies and subterfuge practiced by the different sides of the conflict, including reasons for the timetable of the conflict as prosecuted by Horus, and for the actions of the Emperor as the Heresy was initially unfolding. It starts about 3 months after the Dropsite Massacre, with the unexpected rescue of Corax and the remnants of his Legion (at less than 5% strength). Apparently arriving at Terra a few months after the events described in The Outcast Dead had taken place, Corax convinces the Emperor to impart to him the necessary knowledge and material to accelerate the rebuilding of his Legion, including top-secret gene-stock. The second part of the novel describes the effort to reconstitute the Raven Guard, and the pursuit of opposite objectives by the Alpha Legion. The novel also features a reappearance of the Cabal (Book 7), and of other well-known characters.
