The best Horus Heresy book order

All the Horus Heresy novels in order

1 – Horus Rising

Horus Rising is told mostly from the perspective of the Space Marine Garviel Loken as he is inducted into the inner circle of Horus Lupercal, Warmaster of the Imperium. After centuries persecuting the Great Crusade to reunite the lost worlds of mankind, the Space Marines must confront their assumptions about their place in the universe. Meanwhile, the treacherous Erebus of the Word Bearers begins to enact a scheme that will eventually topple the galaxy.

2 – False Gods

In False Gods, Horus is laid low on the moon of Davin, thanks to a plot by Erebus. In an effort to save his life, his loyal sons deliver him into the clutches of a cult devoted to the ruinous powers of Chaos. Horus awakens a changed man.

3 – Galaxy in Flames

In Galaxy in Flames Horus’ treachery is laid bare. On Istvaan III Horus  and three fellow Warhammer 40k Primarchs – Mortarion of the Death Guard, Angron of the World Eaters, and Fulgrim of the Emperor’s Children – commit the elements of their legion most loyal to the Imperium to a ground assault, before virus-bombing the planet’s surface. Forewarned, some Loyalists survive, and the traitor forces root them out in a gruelling siege.

4 – The Flight of the Eisenstein

The Flight of the Eisenstein begins in the void above Istvaan III, as Captain Saul Garro of the Death Guard is warned of the Warmaster’s treachery. He escapes from the traitor forces in a single vessel and must make a desperate warp-jump towards Terra, all the while contending with the depredations of the Plague God Nurgle.

5 –  Fulgrim

Fulgrim begins before the Heresy, following the perfectionist Emperor’s Children Space Marines as they encounter a strange alien civilization that changes their destiny forever. It ends in the dropsite massacre at Istvaan V.

An Imperial retribution fleet arrives to crush Horus’ rebellion, and is in turn set upon by traitor elements in its own rearguard. Fulgrim faces off against his once beloved brother Ferrus Manus of the Iron Hands in single combat, and slays him.

6 – Descent of Angels

Descent of Angels is set before the outbreak of the Heresy, in two time main periods. On the feudal world of Caliban, the knightly Order purge the great Chaos beasts that haunt the forests and terrorise the innocent. Their leader, the superhuman Lion El’Jonson, is a lost Primarch son of the Emperor, supported by his sworn brother Luther.

55-62 – The Siege of Terra

The Siege of Terra series forms the long-awaited, epic conclusion to all the Horus Heresy’s many plots, machinations, ambushes, and preambles.

Warmaster Horus Lupercal and his vast armada of Chaos Space Marines, traitor 40k Titans, mortal cultists, and daemon allies have at last arrived at the Sol system to launch their final assault on Terra (Earth), aiming to kill and supplant the Emperor of Mankind himself.

There are eight full Siege of Terra novels, one of which is so big it’s split into three parts, plus three novellas – all the main titles and Fury of Magnus are essential reading. This is the crescendo and climax of the whole Heresy series, after all!

• The Solar War
• Sons of the Selenar (novella)
• The Lost and the Damned
• The First Wall
• Saturnine
• Mortis
• Garro: Knight of Grey (novella)
• Warhawk
• Fury of Magnus (novella)
• Echoes of Eternity
• The End and the Death Volume I
• The End and the Death Volume II
• The End and the Death Volume III

As you’d imagine, while there are lots of intertwining, smaller storylines and character groups that run through these novels, each finding some measure of closure in their own stories – the series is effectively one very long book in eight volumes.

In The Solar War, we see the chaos fleet overwhelm the solar system’s outer defences, commanded by master strategist Perturabo of the Iron Warriors.

In The Lost and the Damned, the traitor forces bombard the planet from orbit to the point of environmental destruction, before launching their ground assault on the continent-sized defensive trenchworks surrounding the Imperial Palace.

The attack is led by Mortarion and the Death Guard, joined by his brother Angron of the World Eaters, now a rage-fuelled, daemonic demigod of destruction. Blood Angels primarch Sanguinius flies to the defenders’ aid at key points, but the conclusion is never in doubt.

After a heroic effort, the mostly human Imperial Army defences are overwhelmed – and The First Wall opens with a new focus: the outer walls of the Imperial Palace itself, defended by Rogal Dorn‘s yellow-clad legion of Imperial Fists.

The keystone is protecting the Lion’s Gate spaceport – Terra’s biggest port facility, which, if captured by Horus’ forces, could be used to land their Titan legions on the surface. We, er, won’t spoil how that goes.

Author Dan Abnett’s Saturnine is a more complex read. The Imperial Palace (more a thousand-mile-wide fortress city than a building) has many rings of vast walls and gunlines for the traitor host to fight through and, while they do, each side is watching the clock, watching the skies for incoming Ultramarines, and searching for a cunning master-stroke strategy to turn the tables.

If you like hundred-foot-high battle robots, John French’s Mortis is a hoot. With the traitors well and truly settled on the surface, Horus can finally deploy his titans; the loyalists deploy their remaining titan legions in turn, and we get a series of awesome engine-on-engine confrontations across the blasted ruins of the Outer Palace.

Chris Wraight’s Warhawk is, frankly, a bit of a love letter to Jaghatai Khan and the White Scars. With the traitors closing in on the Inner Palace, the praetorian of Terra Rogal Dorn commands all remaining forces to converge on defensive positions and hold out as long as they can.

But the White Scars don’t like huddling behind walls, and instead sally out to forestall the traitor advance. Watch out for one of the series’ best primarch grudge matches here.

Aaron Dembski-Bowden’s Echoes of Eternity is a gripping study in the unique emotional charge found in the penultimate stages of a siege. Think ‘Aragorn and Theoden in the Hornberg with the Uruk-Hai banging on the door’. Horus’ forces have breached the Inner Palace and are advancing on the Imperial Sanctum – the core building within which the Emperor sits on his Golden Throne.

The Imperial Fists are all but slaughtered; the remaining White Scars are holed up in the faraway Lion’s Gate spaceport; Blood Angels are mostly spent, and beating a fighting retreat. Reinforcements from the Ultramarines appear nowhere near. The end is nigh – but the loyalists fight on.

The final Horus Heresy Siege of Terra book – The End and the Death – comes in three volumes. The Imperium’s last defenders are dwindling; the Imperial Palace is swimming with blood; Terra itself is sinking into the Warp; and Warmaster Horus’s final victory seems inevitable – but, at long last, the Emperor rises from his throne…

This is the Horus Heresy’s absolute finale: the death of Sanguinius and the final duel between the Emperor and Horus aboard the Vengeful Spirit. Beyond that, we’ll have to wait and see…

We’ve included all of the novels and short stories that make a major contribution to each faction, including stories that advance the plot of a legion significantly but only feature them as an antagonist.

Not every story from the Heresy is included: some books and many short stories are self-contained and don’t advance any of the wider character or plot development. Some books appear in multiple reading lists, as they tell two sides of the same conflict.
