Where to start Warhammer 40k books: a beginner's reading list

Nine standalone-friendly first books for the 41st Millennium, chosen by flavour — soldiers, inquisitors, Space Marines, xenos and Chaos — so you can start with the kind of story you already like.

The Black Library catalogue for Warhammer 40,000 runs to hundreds of novels, and the setting itself has ten thousand years of backstory. That looks like a wall, but it is not one: most good entry points are the first book of a series, written to be read with no prior knowledge. You do not need the rulebooks, the tabletop game or the Horus Heresy to begin.

The list below is sorted by flavour rather than by chronology. Pick the section that sounds closest to what you enjoy in other fiction — military drama, detective noir, heroic action, something stranger — and start there. Every book here opens its own series or stands on its own.

Ordinary people in an impossible war

The most common advice for newcomers is to start with human soldiers. They see the galaxy from the ground, they are as baffled by a Space Marine as you would be, and the setting is introduced through their eyes.

First and OnlyDan Abnett · ~765.M41Dan Abnett's first Gaunt's Ghosts novel: Colonel-Commissar Ibram Gaunt and the Tanith First and Only in the Sabbat Worlds Crusade. Trench warfare, a conspiracy against the crusade's leader and a regiment you come to know by name. The series is long, but this book works alone.

For the EmperorSandy Mitchell · 931.M41Sandy Mitchell's Ciaphas Cain is the lighter door into the setting: a celebrated commissar whose heroism is mostly a talent for self-preservation. The war is still grim; the narrator just refuses to be. Start here if you want humour alongside the grimdark.

Investigation and conspiracy

XenosDan Abnett · 240.M41Inquisitor Gregor Eisenhorn hunts a cabal chasing an ancient forbidden text. It reads as a detective story moving through the Imperium's underbelly, and it is one of the most frequently recommended first 40K books. First of the Eisenhorn trilogy.

Space Marines

The armoured giants on every box cover. These three books show them from different angles: a recruit becoming one, a desperate defence, and the new era of the setting.

Space WolfWilliam King · ~659.M41William King follows Ragnar, a tribesman of the death world Fenris, as he is chosen by the Space Wolves and has to master what the transformation wakes in him. An origin story, so the Chapter is explained as Ragnar learns it.

HelsreachAaron Dembski-Bowden · 998.M41Aaron Dembski-Bowden's siege story: Chaplain Grimaldus and the Black Templars hold Hive Helsreach on Armageddon against an ork invasion. Self-contained and often named among the best Space Marine books.

Avenging SonGuy Haley · ~001.M42Guy Haley opens Dawn of Fire, set in the Dark Imperium era after the return of the primarch Roboute Guilliman and the launch of the Indomitus Crusade. Pick it if you want to start in the setting's present day rather than its classic period.

Beyond the Imperial line

Not everyone wants to start on humanity's side. The setting's aliens, traitors and tech-priests have their own entry points.

The Infinite and the DivineRobert RathRobert Rath's Necron novel follows two ancient rivals — Trazyn the Infinite, a collector, and Orikan the Diviner, a chronomancer — across millennia. Witty, strange and entirely standalone; a good choice if you like long-game rivalries more than battles.

The Talon of HorusAaron Dembski-Bowden · ~015.M31Aaron Dembski-Bowden on the other side: the scattered remnants of Horus's Legion in the Eye of Terror, and the search for Abaddon. It is the first novel of the Abaddon the Despoiler series; Black Legion continues the story.

Priests of MarsGraham McNeillGraham McNeill's Forge of Mars opens with an Adeptus Mechanicus explorator fleet heading beyond the edge of the Imperium after a legendary lost expedition. Exploration rather than trench war, with the Machine Cult at the centre.

Bigger projects for later

Some parts of the library are better saved for your second or third book. The Horus Heresy is a prequel era ten thousand years earlier and runs to dozens of volumes; it rewards readers who already know what the Imperium became. The Imperial Guard, the Inquisition, the Adeptus Custodes and the underhive of Necromunda each deserve their own reading order, and we cover them in separate guides.

What next

If one of these books lands, the simplest next step is the rest of its series — each card above links to its reading order. If you want breadth instead, take one book from a different section: a soldier's view after a Space Marine novel, or a xenos story after an Inquisition one. Add what you read to your library on Ordo Lectoris and the tracker will keep your place in every series.
