About The Horus Heresy
The Horus Heresy serves as the foundation for much of the Warhammer 40,000 universe canon. It is a dark, futuristic military space opera that falls within the genre of dystopian science fiction, but fans of grimdark fantasy will be sure to enjoy this world as well.
However, there is a lot to cover. That’s because there are 54 books set within the original main series, an additional 18 set within the Siege of Terra era, and 17 full-length novels all about the Primarchs. And that’s not to mention more than 100 other books, short stories, novellas, and audio dramas.
There has been a significant increase in the popularity of Warhammer in recent years, which means there are many new fans entering the fray for the first time. The sheer number of stories available can be overwhelming, especially when you take into consideration that the Horus Heresy is the precursor to Warhammer 40k.
The majority of the Horus Heresy stories take place in the 31st millennium. The books, novellas, and short stories we’re about to dive into detail the conflict that took place between the Imperium’s founder and leader, the Emperor of Man, and the Warmaster Horus. These are the stories of the first trickles of Chaos infiltrating Horus and the darkness which descended.
Thankfully, it is not necessary to read all the books in the main series to fully grasp the plot, tone, and intention of the Horus Heresy. That’s because this series tells the story of this era from multiple perspectives.
Once you have a solid understanding of the world and its key players, then you’ll be able to explore the universe at your will and leisure. You can explore the factions, the characters, or a favorite author which interests you the most.
Horus Heresy Reading Order
The Original Horus Heresy Books
This is the recommended beginning to any Horus Heresy reading order and it is most important to begin by reading the first five books in order of publication. While the books are written by different authors, the first three books act as an introductory trilogy to the series. The next two books then fill in more of the gaps and provide more context.
The Horus Heresy books will introduce you to a galaxy in the aftermath of the Great Crusade as the Emperor celebrates his victory, but such tenuous peace never lasts. The Emperor’s most loyal soldier, Horus, is tempted by the Chaos gods and defects. His defection shatters the compliance left in the wake of war and a new battle begins.

Summary of the Horus Heresy Reading Order
As we’ve already said, the best place to begin the Horus Heresy reading order is with the original series. At the very least the first arc which unfolds within the first five books should be read in order. This will give you the necessary understanding and context for which everything else is built upon.
Within the original 54 Horus Heresy books there are multiple arcs following different characters. Below you will find the summaries to the first ten titles which includes nine novels and one short story collection.
1. Horus Rising
After thousands of years of expansion and conquest, the Imperium of Man is at its height. His dream for humanity nearly accomplished, the Emperor hands over the reins of power to his Warmaster, Horus, and heads back to Terra. But is Horus strong enough to control his fellow commanders and continue the Emperor’s grand design?
2. False Gods
The human Imperium stands at its height of glory. Thousands of worlds have been brought to heel by the conquering armies of mankind. At the peak of his powers, Warmaster Horus wields absolute control – but can even he resist the corrupting whispers of Chaos?
3. Galaxy in Flames
Having recovered from his grievous injuries, Warmaster Horus leads the triumphant Imperial forces against the rebel world of Isstvan III. Though the rebels are swiftly crushed, Horus’s treachery is finally revealed when the planet is razed by virus bombs and Space Marines turn on their battle-brothers in the most bitter struggle imaginable.
4. The Flight of the Eisenstein
Having witnessed the events on Istvaan III, Deathguard Captain Garro seizes a ship and heads to Terra to warn the Emperor of Horus’s treachery. But the fleeing Eisenstein is damaged by enemy fire, and becomes stranded in the warp. Can Garro and his men survive the depredations of Chaos and get his warning to Terra in time?
It is the 31st millennium, and humanity is at the peak of its powers. As the Great Crusade, led by Warmaster Horus, continues to conquer the galaxy, Fulgrim, Primarch of the Emperor’s Children, leads his warriors into battle against a vile alien foe.
From the blood of this campaign are sown the seeds that will lead this proud Legion to treachery, taking them down the darkest of paths of corruption. Leading up to the carnage of the Dropsite Massacre on Isstvan V, this is the tale of Fulgrim’s tragic fall from grace.
6. Descent of Angels
This is the next novel in the ground-breaking, bestselling series that tells the story of the Horus Heresy – the civil war that nearly tore the human Imperium apart, ten thousand years ago.
This novel explores the early history of the Dark Angels Legion and their Primarch Lion El’Johnson. When news of Horus’s treachery reaches Caliban, the loyalties of this proud and mysterious Legion are tested to the limit, with tragic consequences.
A Great War is coming, and it will engulf the Imperium of Man. The Space Marines of the Alpha Legion are the last and most secretive of all the Astartes brotherhoods. They arrive on a heathen world to support the Imperial Army in a pacification campaign against strange and uncanny forces.
But what drives the Alpha Legion? Can they be trusted, and what side will they choose when the Great War begins? Loyalties are put to the test, and the cunning schemes of an alien intelligence revealed, as the fate of mankind hangs in the balance.
8. Battle for the Abyss
Now that news of Horus’s treachery is in the open, a time of testing has come. Some Legions have already declared their allegiance to the Warmaster, while the loyalty of others lies firmly with the Emperor.
As Horus deploys his forces, loyalist Astartes learns that a massive Wordbearers fleet is heading to Ultramar, home of the Ultramarines. Unless they can intercept the fleet, and destroy the mighty battleship that has been sent to reinforce it, the Ultramarines may suffer a blow from which they will never recover.
As the flames of treachery spread throughout the Imperium, Horus plots to subvert or destroy all those who would stand against him.
On Mars, home world of the Mechanicum priesthood, the great manufactory-cities have long produced much of the weaponry required for the expeditionary fleets across the galaxy. Thus, making the world invaluable to whoever controls it in the coming war.
Now, the Warmaster’s agents begin to stoke the fires of rebellion, turning the loyalist forges and the mighty Titan Legions against one another. And, with whispers spreading of an ancient terror lurking beneath the Red Planet’s surface, the Dark Mechanicum rises…
10. Tales of Heresy
When Horus the Warmaster rebelled against the Emperor, the ensuing civil war nearly destroyed the Imperium. War raged across galaxy, pitting Astartes against their battle-brothers in a struggle where death was the only victor.
This is an anthology featuring short stories from the Horus Heresy era, including Dan Abnett, Graham McNeill, James Swallow, Mike Lee, and more.
Final thoughts on the Horus Heresy Reading Order
Beginning to read the Horus Heresy books can be overwhelming to say the least. There are more than 90 full-length novels and hundreds more stories in various forms. However, the beauty of such an expansive universe is that once you’ve established the foundation for yourself, there are galaxies to explore at your leisure.
After you’ve read the first five books in the original series, that foundation has begun to be built around you. It is best to then read the other full-length novels, so you will have a solid understanding of the key players and moments within the Horus Heresy.
Following the publication order means you will avoid spoilers as you learn more about this universe. Then, as you become more comfortable and identify your favorite characters, authors, and battles, you can find the supplemental stories to enhance your Warhammer reading journey even more.
