Book Review: The First Wall by Gavin Thorpe — A Newcomer’s Perspective on the Siege of Terra
As someone relatively new to the sprawling Warhammer 40,000 universe, I approached The First Wall—the third installment in the Siege of Terra series—with both excitement and a bit of trepidation. After thoroughly enjoying the first two books, which introduced me to the vast and brutal conflict surrounding the Siege, I was eager to dive deeper into the layers of this epic saga. Gavin Thorpe’s The First Wall did not disappoint; it delivered a gripping continuation that expanded my understanding of the Warhammer mythos while maintaining the visceral, high-stakes intensity that hooked me from the start.
Plot and Themes
The book plunges directly into the escalating brutality of the Siege of Terra’s next phase, focusing on the massive, bloody clash at the Lion’s Gate spaceport—a pivotal strategic point. Thorpe does a fantastic job portraying the sheer scale and ferocity of the battle, throwing the reader into the chaos of thousands of combatants locked in desperate struggle. The narrative centers on Perturabo, the Iron Warriors Primarch, who is portrayed as a grim, ruthless tactician determined to prove his worth to Horus and to outshine his loyalist brother, Rogal Dorn. This family rivalry adds a compelling emotional undertone to what could otherwise be a straightforward siege story.
The introduction of Warsmith Kroeger as Perturabo’s blunt instrument brings a gritty, brutal edge to the fighting. Kroeger’s relentless, merciless assault feels like a force of nature—unstoppable, devastating, and terrifying. Watching the Iron Warriors and the Imperial Fists go head-to-head in this relentless battle gave a real sense of the horrors of war at both a personal and planetary scale.
Meanwhile, the story also weaves in intriguing subplots that broaden the scope of the conflict. Custodian Amon Tauromachian’s investigation into the rise of the Lectitio Divinitatus within the Imperial Palace adds a layer of political and metaphysical intrigue, which I found fascinating despite my limited prior knowledge. It hints at how belief, power, and corruption intertwine in the Imperium’s highest echelons.
Additionally, Thorpe takes us far from Terra itself, introducing the proud volunteers from Addaba Hive and their arduous journey to Himalazia. This subplot enriches the world-building, reminding the reader that the Imperium’s struggle is felt across countless worlds, each with its own sacrifices and heroes.
Writing Style and Accessibility
One of my biggest concerns as a Warhammer newcomer was whether the complex lore and massive cast of characters would be overwhelming. Thankfully, Thorpe strikes a good balance between detailed exposition and fast-paced action. While some familiarity with the universe certainly helps, the narrative manages to convey the stakes and motivations clearly enough that I never felt lost or confused.
The prose itself is vivid and immersive, often gritty and unflinching in its depiction of war’s brutality, which suits the subject matter perfectly. The pacing keeps the tension high throughout, mixing sweeping battlefield sequences with intimate character moments that give the story emotional depth.
Character Development
The characters in The First Wall feel larger-than-life yet layered. Perturabo emerges as a complex figure—hard, proud, and desperate for validation, yet with a certain tragic grandeur. The rivalry with his brother Dorn adds a humanizing element, showing that beneath the armor and war machines are real, flawed personalities.
Kroeger is terrifying and relentless, embodying the Iron Warriors’ reputation for cruelty and efficiency, but Thorpe doesn’t reduce him to a mere villainous archetype. Similarly, Amon Tauromachian’s subplot introduces a custodian with a strong sense of duty and insight, providing a contrasting perspective on the siege’s toll.
Overall Impression
For someone still getting their footing in the Warhammer 40K universe, The First Wall is an impressive continuation of the Siege of Terra saga. It deepens the scope and stakes of the conflict, showcasing brutal battles, intricate political-religious undercurrents, and far-reaching consequences across the galaxy. Gavin Thorpe manages to keep the story accessible without sacrificing complexity or depth.
If you enjoyed the first two books, this one is a must-read. It enhances the emotional resonance of the siege and provides new layers of intrigue and action that make the saga feel truly epic. Even as a newcomer, I found myself more invested in the characters and eager to see where the war goes next.
Rating: 4.5/5 stars
