The Siege of Terra reading order

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!

I – The Solar War

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.

Sons of the Selenar (novella)

In Sons of the Selenar, the remnants of Shadrak Meduson’s shattered legions attempt one last mission, to stop the Sons of Horus from claiming the genetic alchemy of the Selenar genecults on Luna.

II – The Lost and the Damned

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.

III – The First Wall

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.

IV – Saturnine

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.

Fury of Magnus (Novella)

In Fury of Magnus, Magnus the Red seeks an audience with his father – or, perhaps, his father is seeking an audience with him. Is there any possibility of redemption for a son so far fallen to ruin?

Warhammer artwork showing battle titans in the Horus Heresy era

V – Mortis

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.

Garro: Knight of Grey (Novella)

Amid the ruins of the Imperial Palace, Nathanial Garro, Knight of Grey struggles to protect Euphrati Keeler, the first saint of the Imperial Church. He will face off against his greatest foe, his genefather, Mortarion, Primarch of the Death Guard.

VI – Warhawk

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.

Warhammer 40k Horus Heresy book order - Games Workshop artwork showing Blood Angels Primarch Sanguinius on the steps of the Imperial Sanctum

VII – Echoes of Eternity

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.

VIII – The End and the Death

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…

Warhammer 40k Horus Heresy book order - Games Workshop graphic with a text excerpt introducing the final books

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…

The best Horus Heresy books for each legion
