The Horus Heresy (Novels)

The Horus Heresy series is a collection of novels, novellas, short stories, and audio dramas written by some of the Black Library's best-known authors. It chronicles the history of the Horus Heresy era which serves as the foundation and starting-point for most Warhammer 40,000 canon. The series began in 2006 with the publication of Dan Abnett's Horus Rising and as of July 2014 consists of thirty-one novels written by over eighteen different authors. There are many more books in the series already being prepared for publication in 2015 and beyond. While the novels do deal with a continuous stream of events it is possible to approach most of them in any order one likes.

Titles
The following is a list of the current titles in the main Horus Heresy novels series:

Synopses
The novelisation of the Horus Heresy is not strictly sequential and the story of the Heresy may be presented in a non-linear chronology from book to book; novels may concern events in the Heresy that happen earlier than their position in the series would suggest, or may include time periods already covered in other books of the series.

Horus Rising details the rise to power of the Warmaster Horus, Primarch of the Luna Wolves Legion, after the Emperor of Mankind appoints him commander of the Imperial military and places him in charge of the Great Crusade. Much of the focus is on the Captain of the Luna Wolves' 10th 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.
 * 1. Horus Rising - The seeds of heresy are sown

False Gods describes Horus' fall to Chaos. In a complicated conspiracy implemented by the servants of Chaos within the Word Bearers Legion, 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.
 * 2. False Gods - The heresy takes root

Galaxy in Flames concerns the virus-bombing of Istvaan III and the Warmaster Horus' ultimate fall into madness, which resulted in a galactic civil war where brother would fight brother. In the virus-choked wasteland of death and destruction that was once Istvaan III's Choral City, Loyalist elements of the Luna Wolves, World Eaters, Emperor's Children and Death Guard Legions fight against the Traitors of those Legions in a desperate show of defiance, as the first move of the Heresy is played out.
 * 3. Galaxy in Flames - The heresy revealed

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 who remained Loyal to the Emperor. The novel follows the Eisenstein's escape from Istvaan III (see Galaxy in Flames above) and its voyage across the galaxy in an attempt to reach and warn the Emperor of Mankind on Terra.
 * 4. Flight of the Eisenstein - The heresy unfolds

Fulgrim centres around the Primarch of the Emperor's Children Legion, Fulgrim, 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 Legion also play a prominent role in the novel, and the pivotal Battle of Istvaan V (the so-called Drop Site Massacre) is described in passing.
 * 5. Fulgrim - Visions of treachery

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 (a monastic order of techno-barbarian Calibanite knights). The first half of the novel is set on Caliban and covers the final battles of The Order under the future Primarch of the Dark Angels Space Marine Legion, Lion El'Jonson. 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 an Aspirant Space Marine, is ultimately accepted as a Neophyte of the Dark Angels Legion. A future schism within the Legion is intimated in this section of the book.
 * 6. Descent of Angels - Loyalty and honour6._Descentofangelscover.jpg

Legion features the Alpha Legion, the XX Astartes Legion (and last to be formed), which was known as the most secretive and inscrutable of all the Space Marine 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.
 * 7. Legion - Secrets and lies7._Legion.jpg

Battle for the Abyss describes the lead-up to the Battle of Calth fought between Primarch Roboute Guilliman's Ultramarines and the Word Bearers Traitor 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, the Realm of 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.
 * 8. Battle for the Abyss - My brother, my enemy8._Battle-Abyss.jpg

Mechanicum is about the civil war or Schism of 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 Mechanicus Adepts who plot and eventually carry out a coup d'etat in order to eliminate those on Mars who remain Loyal to the Emperor.
 * 9. Mechanicum - War comes to Mars9._Mechanicum.jpg

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.
 * 10. Tales of Heresy 10._Tales-of-heresy.jpg

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 to Horus' forces on Isstvan; the other of Luther (Lion'El Johnson's second-in-command within the Legion), 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.
 * 11. Fallen Angels - Deceit and betrayal11._Fallen-angels.jpg

A Thousand Sons is the story of Magnus the Red and the Thousand Sons Legion of Space Marines, and for the most part takes place before the Heresy begins. Following a reprimand by the Emperor of Mankind for dabbling in sorcery, 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 Leman Russ and his Space Wolves Legion, accompanied by other Imperial forces, to bring Magnus and his Legion to Terra to account for themselves.
 * 12. A Thousand Sons - All is dust...12._A-thousand-Sons.jpg

Nemesis is set about two years after the events on Istvaan 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 Word Bearers Traitor Legion the idea to field a nemesis weapon of his own (a highly specialized assassin) in an audacious scheme to kill the Emperor.
 * 13. Nemesis - War within the shadows13._Nemesis.jpg

The First Heretic details the fall to Chaos of Primarch Lorgar and his Word Bearers, the XVII 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 Terran years, starting 47 years before the events on Istvaan 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 XVII Legion by the Emperor himself for introducing religious worship of the Emperor as the God of Mankind on the world of Khur, Lorgar is swayed by two of his most trusted lieutenants Kor Phaeron and the the Chaplain Erebus, who were already in secret allegiance with Chaos. Eventually both Primarch and his Legion abandon the Imperium following the Pilgrimage of Lorgar into the Eye of Terror, and in full accord with Horus take part in the Istvaan V Drop Site Massacre.
 * 14. The First Heretic - Fall to Chaos14._The_First_Heretic--.jpg

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 the Warmaster Horus's fall to Chaos, thus providing a more coherent view of the Heresy and of its planning by the Chaotic forces.

<p style="line-height: 19px; color: rgb(0, 0, 0); font-family: sans-serif; background-color: rgb(255, 255, 255);">Age of Darkness is a compilation of short stories providing background information on the Horus Heresy. These stories cover the seven-year period between the Drop Site Massacre on Istvaan V (Book 5) and the start of the final campaign against Terra by the Traitor forces.
 * 16. Age of Darkness - The age of knowledge and enlightenment has ended. The age of darkness has begun16._Age-of-darkness.jpg

<p style="line-height: 19px; color: rgb(0, 0, 0); font-family: sans-serif; background-color: rgb(255, 255, 255);">The Outcast Dead is the first novel in the series to take place entirely on Terra. It covers a relatively short period, from shortly before the Drop Site Massacre at Istvaan V (Book 5), to shortly after Primarch Magnus's catastrophic psychic visit to the Imperial Palace (Book 12), an event that is central to the tale. The main character is Kai Zulane, previously a gifted Astropath attached to the Ultramarines Voidship Argo. He unwittingly becomes the keeper of a secret -- how the Horus Heresy will end -- that could decide the victor in the developing galactic civil war. The Outcast Dead are a small, disparate group of Space Marines drawn from several different Legions who are suspected to be 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, which provides one explanation for the post-Heresy scientific and cultural stagnation of the Imperium of Man.
 * 17. The Outcast Dead - The truth lies within17._The-Outcast-Dead.jpg

<p style="line-height: 19px; color: rgb(0, 0, 0); font-family: sans-serif; background-color: rgb(255, 255, 255);">Deliverance Lost concerns the actions of the Primarch Corvus Corax and the XIX Space Marine Legion, the Raven Guard, during the year following the Drop Site Massacre on Istvaan V (Book 5). However, covert operatives and the Primarchs Alpharius Omegon of the Alpha Legion (Book 7) play prominent roles. 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 Warmaster Horus, and for the actions of the Emperor as the Horus Heresy was initially unfolding. The story begins approximately 3 months after the Drop Site Massacre, with the unexpected rescue of Corax and the remnants of his Legion (at less than 5% strength) from Istvaan V. Apparently arriving at Terra a few months after the events described in The Outcast Dead (Book 17) had taken place, Corax convinces the Emperor to impart to him the necessary knowledge and material to accelerate the rebuilding of his Legion, including the top-secret remnants of gene-stock left over from the original Primarch Project. The second part of the novel describes the effort to reconstitute the Raven Guard, and the opposition to this by the hidden operatives of the Alpha Legion. The novel also features a reappearance of the Cabal (Book 7), and of other well-known characters from previous books in the series.
 * 18. Deliverance Lost - War within the shadows18._Deliverence_lost.jpg

<p style="line-height: 19px; color: rgb(0, 0, 0); font-family: sans-serif; background-color: rgb(255, 255, 255);">Know No Fear documents the Word Bearers' surprise assault on Calth, a world belonging to the Ultramarines and the subsequent course of the infamous Battle of Calth. The story starts close to where the timelines of Battle For The Abyss (Book 8) and The First Heretic (Book 14) converge. The invasion is planned and lead by the Traitor Primarch Lorgar, now fully and openly committed to the spread of the worship of Chaos. The story starts with the invasion force en route to Calth. The objective is to completely destroy the Ultramarines Legion, the largest of all the Space Marine Legions, and by doing so, cause the creation of Warp Storms due to the destructive energies unleashed by the war. The Warp Storms would isolate and confuse the Ultramarines forces and effectively neutralise them for the remainder of the Horus Heresy. The Word Bearers are also offering this slaughter of Loyalists as a tribute to their new Gods of Chaos. The story tracks the campaign from its opening phases and the actions of several characters. It is a bloody war with dark ritualistic undertones, scorched earth tactics, decisive use of technology, and the considerable involvement of Chaos.

<p style="line-height: 19px; color: rgb(0, 0, 0); font-family: sans-serif; background-color: rgb(255, 255, 255);">The Primarchs is an anthology composed of four novellas which focus on some of the mightiest warriors and leaders that Mankind has ever known -- the Primarchs Fulgrim, Lion El'Jonson, Ferrus Manus, and Alpharius Omegon -- and the roles that they may have yet to play in a galaxy-wide civil war which threatens to change the face of the Imperium forever.

<p style="line-height: 19px; color: rgb(0, 0, 0); font-family: sans-serif; background-color: rgb(255, 255, 255);">Fear to Tread takes place upon the war-torn world of Signus Prime. Warmaster Horus sends the Blood Angels Legion to the Signus system on a fool's errand, where a large host of Chaos Daemons awaits them. The Warmaster's plan is to exploit the flaw in the Blood Angels' gene-seed (which will later be known as the Red Thirst) in order to turn them to the worship of the Blood God Khorne. The Blood Angels are forced to fight for their very survival of both their minds and bodies. At the height of the battle, Primarch Sanguinius is confronted by the mighty Bloodthirster Ka'Bandha.

While the Traitor Legions continue their campaign of terror across the galaxy, preparations are made for the defence of the Imperial Palace and the final, inevitable reckoning that must yet come between Horus and the Emperor of Mankind. In the first novella, Crimson Fist by John French, we learn of the fate of Primarch Rogal Dorn and his Imperial Fists fleet originally sent to Istvaan III. In the second novella, Prince of Crows by Aaron Dembski-Bowden, the story descends deeper into the darkness of the Night Lords Legion.
