Death Rider is the debut novel of Rhuairidh James, who has previously written several short stories and a novella for the Black Library. I really fell in love with some of his previous works, especially with the short story 'The Sum of its Parts' and the novella 'Da Gobbo Rides Again', which is why I had very high hopes for his first full-length novel.

These admittedly high expectations have widely been met. Death Rider is an exploration of the Imperium, the people it chews out and chews through and what happens when the Imperial war machine grinds to a halt and starts to eat itself.

James has previously written for the satirical website The Regimental Standard, which shows in the subtle (sometimes outright, mostly gallows) humour that runs through his writing. This is not a funny book, though. It's an exploration of the cruel realities of the 41st millennium and what the Imperial system does to its people, the callousness and the cruelty of the Imperial warmachine and its propaganda apparatus.

There's a deeply humanistic streak to James' writing, which shows in the empathy and depth with which he reaches out to his characters. It reminded me of Remarques' writing in All Quiet On The Western Front - not just the surface similarity of the content of the grim realities of trench war (which are or course a major influence on the conceptualization of the Death Korps of Krieg in general), but also in the sensitivity with which both authors approach the way that the human psyche reacts to inhuman conditions and the deep compassion they show towards people who have to sacrifice most of their humanity to live another day - and how these people can still cling on to a spark of their humanity despite that.

The characters are largely people which the imperium has tried its very best to rob of their humanity to turn into more effective tools: tools of war, tools of oppression, tools of control.

There's Valian Hesh, our primary protagonist, a commissar who doesn't like to kill people (attached to the Korpsmen of Krieg, but not born there). James doesn't go the simple route with this premise to simply write Hesh as a Generally Good Guy who just happens to be a commissar (which one might accuse certain other literary commissars to be an example of), but really digs into the complexity of the interaction between a role in which murder of your subordinates sits at the top of the job description and the person inhibiting it. During the first 100 pages or so, I was almost irritated by Hesh because I couldn't really get a fix on what his character was supposed to be: a fraud? A killer? A coward? A hero? A monster? A competent player, an unwilling participant, or a determined opportunist? As the book went on, I realized that this was a feature, not a bug, and that this question is at the heart of the novel and that the answer is neither clear nor simple.

Then there's Jens, Hesh's Krieg-born adjutant. Because Hesh and Jens start the novel out separated from the actual Krieg regiments on Rezlan VI, Jens is (beside Hesh's own musings and recollections) for large parts of the book our primary window into the Krieg culture and the reactions the Korpsmen get from other Imperial citizens/soldiers. Like Hesh, she gets slowly more developed over the course of the book and we get to learn her as both an exemplar and an exception to the assumptions Imperials (and we as readers) have towards the Krieg. The understated and professional, but subtly almost tender relationship between Hesh and her - both people hammered in a particular shape by an utterly inhuman and cruel system - is one of the highlights of the book.

There are other secondary characters like Hesh's Krieg-born, chemically altered, hulking "horse" (big quotation marks here) and a variety of Imperial military personnel that get encountered along the way that enrichen the story and show James' faible for the colourful shades of Imperial regiments and planetary cultures. Some of these feel a tad underdeveloped and I would've liked to spend more time with them, although James uses the page time that he has for these characters well.

In terms of antagonists, the book has three major one, by my count. On one hand there's the external enemy, the T'au; like the remnants of the Imperial war force, they are with their backs to the wall on Rezlan VI, and it shows in the way that they approach their enemy: clinical and utterly destructive. Then there's Katarin, Hesh's former tutor/torturer at the Schola and beyond, who returns to Hesh's life as acting lord-commissar on Rezlan VI. She's one of the highlights of the book for me, a snarling, commanding presence whose cruelty is only matched by her competence. And the final antagonist is the Imperial system itself: the book really hammers home that, despite anything that might happen on Rezlan VI for good or bad, the characters will *still be part of the Imperium* afterwards and will have to deal with the aftermath as such; the threat of a follow-up investigation of anything that transpires here is a sword of Damocles that carries on throughout the novel and shapes the behavior and tactics of the characters almost as much, if not more, than the dangers on the planet itself.

The book struggles a bit in the early action scenes. There are three major action set-pieces, and I found the first two to be a bit of a speed bump to my enjoyment of the novel. They're not *bad* at all and there are good ideas in terms of set-up and thematic relevance for the novel, but they were a bit confusing to follow for me and felt like they dragged on a bit longer than they needed. To be honest, this being a debut Black Library novel, it felt a bit like these were scenes that had to be included because this is a WARhammer book after all and not because they emerge naturally from James' strengths as a writer. The third and final action set-piece (and the final act as a whole) though really shifted gears and - because it multiplies the chaos and madness that is going on, which eschews the need to follow a beat-by-beat scene progression like in a tank chase or an infantry ambush - turned the bugs of the earlier action scenes into features for the final one, and the third act really shines for it for it's pacing, intensity and how it viscerally pays off the various setups of the earlier parts of the book. Talk about going out on a high note!

Something I really enjoyed (and where James' Regimental Standard experience showed again) was the backdrop of this being part of Imperial history books, with Historical Notations on events framing the story, giving context for the history that will be written from the actual events that we as readers can participate in.

The plot of the book, while on the face of it having a simple "Go from A to B and back to A again" mission as its central throughline, avoids becoming too predictable or linear and, without spoiling too much, has a few aces up its sleeve without ever becoming contrived.

That all being said, even with a few bumps in the road and some rookie mistakes here and there, Death Rider sticks the landing and stands as an impressive debut by one of Black Library's most promising, distinct young voices - Rhuairidh James is an author that excites me by the way *how* he writes, not just *what* he writes about, which is always a good sign. The books ends on a, in my view, perfectly calibrated note and sent me out of it with a smile on my face, a lump on my throat and a tear in my eye. I'm really looking forward to anything that Rhuairidh James will write next, and I hope that this book will make the rounds beyond the die-hard Krieg fans, because it's an example for a nuanced, empathetic and subtly idiosyncratic piece of literature for the 41st millennium, of which there can't be enough.

Author’s Debut is a Knockout

By design, Krieg are faceless and somewhat hard to care about as individuals. This story made me genuinely care about Hesh and Jens in a way that many of 40K’s mainline multi-book series never achieved. Black Library’s average fare falls into one of two traps. Either ‘These named characters have models and therefore definitely aren’t dying’ or ‘I don’t give a shit if this character who CAN die actually does or not’. Death Rider is a satisfying example of having both stakes and compelling characters, and I hope James becomes a recurring author in BL’s stable.

[Sarah Kaiser · Rating 5 out of 5]

A really cool look into the humanity buried behind the masks of the Death Korps of Krieg, their fascinating background (that had felt bare-bones and mysterious before now) - and a truly horrific horse future. In addition, the prose style is gripping - especially during combat and frantic, harrowing sequences - and it really pulls you along from start to finish.

All in all, over much too quickly! I hope to see more of Jens in the future.

Read because: You enjoy a great BL novel, Kriegers, or think horses are a ripe canvas for horrors unimaginable.

This was the first 40k book I have read. I mainly bought it because of the descriptions of the Tau, and was somewhat disappointed. However, I really liked the descriptions of the Krieg, and especially the horses(0_O). The t'au battles were a little lackluster, but many of the other battles and the scenes in between were very well done. My only major complaint was that some groups' actions were a bit confusing at the end ***SPOILER***when the CCA's scheme with the t'au was revealed, I had to reread the passage several times to figure out who was deceiving who, etc. Additionally, in the final battle, I was a bit confused as to why the Navy attacked until I re-read the initial pages when Hesh arrives at the Point of Absolute Failure. this is pretty easily overlooked, though, because the book is great overall.

Death Rider -
A death korps of krieg book
In which an imperial commissar gets himself an autistic horse girl baddie from krieg. Fighting through a nuclear wasteland to save lives he first must deal with unresolved mommy issues.

[Adam Colclough · Rating 5 out of 5]

Easily the best Kreig book I've read, and the best Black Library book of 2026 so far. This one is clearly flying under the radar a bit looking at the number of reviews, but I cant recommend this enough. Looking forward to whatever Rhuairidh James does next.

[Darren Chaplin · Rating 4 out of 5]

It is a fantastic book if you are looking for a good and human and personal story of a Death Rider commissar which I very much enjoyed.

However if you’re looking for a book solely for the Death Riders and their operations you might be disappointed.

Best Kreig novel

Excellent description of a comissar's challenge of being assigned to Kreig, the making of a comissar and the use of the kreig Calvary

[Paul Sparks · Rating 5 out of 5]

A Kreisler book that’s actually more of a commissar book, I quite enjoyed it

[Skywatcher Adept · Rating 1 out of 5]

This is not a book about Krieg Death Riders. This is a book about Commissar Hesh, his female Krieg adjutant and a mixture of Krieg, Attillan rough riders, Mordian tankers, local Rezlan guard, Navy Breachers, other Commissars and other Imperial Guard regiments.

Death Riders appear here and there, we have brief glimpses into their culture, but they drown in the flood of other Guard units shown on screen. The Commissar calls his gigantic steed "Alice".

Hesh's hodge-podge team of Guardsmen & Guardswomen fights a few skirmishes with a Kroot warband, a couple of Tau drones or human Tau auxiliaries but very rarely fights the classic Tau. There is some kind of proper battle against the Tau in the latter part of the book when Hesh finally joins the 472nd Siege Regiment but it's rather briefly described.

The final battle of the book and the main charge of the Death Riders is directed against other Imperial Guard units, not against the Tau. The book in general is about Imperial humans killing each other, not the Tau.

Hesh's adjutant Jens keeps taking off her mask throughout the book and the Death Riders also take off their masks before they final charge. It is incredibly anticlimactic.

Death Riders are one of the most unique units in the Imperial Guard and they deserve much better than this book.
