SPOILER REVIEW WARNING (more a comparison of Fall of Cadia and Cadia Stands as both attempt to expand on the siege of Cadia plot point.
LISTENED TO AUDIOBOOK(audiobook is a must-recommend; David Seddon can make good voice acting for chill or stressed characters. He can be quite refreshing when you are used to Jonathan Keeble)
The Fall of Cadia campaign book really sucked as much for its rushed passing and lack of detail for what has been hyped as a battle for the fate of empires. For me personally, I really couldn't stand the book, wishing we'd gotten an imperial armour-sized book, not to mention some exciting rules to simulate Cadia as a battlefield, but that was ages ago, and by then, 40k had moved on to a new premise. Then 'Cadia Stands' by Justin D Hill came out and suddenly made the whole thing enjoyable and gave much-needed depth compared to the campaign book(kinda like SW3 novelisation). Then, last year, the 'Fall of Cadia' Novel by Robert Rath came out.
'Fall of Cadia' is a Dune-sized book with many characters and separate theatres that seem to combine into a conclusion. If you want a book that gives you lore, you can use it in your next lore battle, and you'll love it. If you want a more refreshing view of Creed, Abaddon, the black legion and Cadians, you'll love it even more.
I rarely give anything five stars, but I need help to think of many wh40k novels that have contributed to world-building and storytelling like Rob Rath did 'Fall of Cadia'. Rather than just say why this is good like everyone else or look for pieces to pick at, I'd instead compare it to other attempts at explaining Cadia's Fall and the Cadians themselves.
'Cadia Stands' presents the conflict through the narrator's objectivity in describing events while the characters deal with their own problems. The plot revolves around Creed, without him really being the main character. It's only 8hrs long but goes through events relatively quick. A decent build-up is set up for the final engagement, only to be met by the plot, forcing the characters to escape and survive. Not to mention, The Sons of Malice get a cameo. What Rob did differently was not only did he ramp up the scale with nearly 20 hours ' worth but also thought critically of what was already written down and applied that to existing real-world examples. He points out the likely problems of such a society mentioned in novels and codexes. Through guardsmen and even spies, we get an insight into what cadian society really is. It's no meritocracy as lineage is valued just as much as skill; soldiers enjoy privileges even the most skilled of civilian workers are denied. Alienation through feudal classes results in a caste of potential rebels, from criminals to cultist activity. We like to imagine the whole society as regimented and ordered, but little do we think about what that means for those who consider it less of a priority. Class struggle isn't anything new in cadian or 40k books. Creed's short stories and 'Cadia Stands' make that clear, but through this choice of critical world-building, he gives readers more perspective of how the imperial war machine works and what costs it comes at.
Creed is also given a new perspective that could have risked character assassination, but instead, we get a more complete character. Creed was a very memeible character, almost like an anime strategist protagonist pulling traps out of thin air whilst giving cool speeches. In his short stories, we get reasons as to why he ends up ruling a planet when he was only previously a Young general(by guard standards). 'Cadia Stands' promotes what makes him a skilled leader by using the trick of seeing it from the eyes of others. However, in 'Fall of Cadia', he is explored more as a character by outlining his weaknesses as a leader. He is presented as a fish out of the water(not the wholesome kind, the asshole kind); his in-experience as a statesman and politician really hurts the war effort as he is unable to manage the byzantine scale of the imperium's factions. His military genius, however, is not sacrificed in the writing as it's clear his skill as a general does impact the war. His personality is shown to be more akin to that of the Primarch Lion el Johnson. As a result, this doesn't retcon but instead expands on Creed as a personality; he feels more fallible of a human and one of the few left who can be counted on despite his flaws. His most prominent advantage is how his troops see him as a genius when, in reality, he is just as flawed as the rest of them. On the other hand, Cadia Stands presents him as an unorthodox hero who pushes people past the limit with inspiration and cunning.
The war itself is presented at its late stage; the walls are worn down, the rations low and the troops are low. We see the motives behind the decisions made, giving readers an impression of why politicking is critical in war. His writing style provides new information and scale to the conflict; all the events and descriptions of the environment events and scenes are intense. Cadia Stands feels more cinematic and is based on troop movements alongside character actions. There's less of a focus on how to the limit things really are and more on what the Cadians did to triumph. 'Cadia Stands' presents the chaotic assault as ferocious but intensely hitting itself against the wall until it breaks. Giving the impression that it took immense losses to make progress further gave the cadian shock more prestige in the book and the idea that the black legion was unprepared. However, black legion characters in 'Fall of Cadia' provide insight into what they had access to and saw Cadia as objectively. Abaddon's scenes are critical as they also show how little he wanted to expend on Cadia and how he keeps control of the black legion.
The best character in the book is Gent, a mob boss who runs a criminal syndicate. His purpose as a character to the setting finally gives us readers an insight into what it is actually like to live on Cadia as a civilian, and it ain't pretty. He is by far the best character due to his unique personality and apathy for the imperium and the war itself; he also provides neat lines, giving him a proper edge in a setting that cuts itself. 'Cadia Stands' focuses entirely on soldiers and the fighting, yet Rob's choice of describing the living conditions and applying them to the war effort with a plot line around ration cards and the black market. Gent's existence alongside a black legion operative has shined a light on how life in Cadia is unfair and has alienated the masses for the purpose of glorifying militarism.
Does this book make 'Cadia Stands' obsolete though... Nope. The writing styles are quite different, and the areas of depth vary. 'Cadia Stands' is shorter and still a cool read, if you are looking for a book that makes the original campaign book topic engaging. What it really does well is give an insight into what was needed to make things work(e.g. the massive reserve counterattack) and why Creed is liked. The book is more of a conceptual description of the war, an example of the struggles guardsmen have to deal with. But Rob's 'Fall of Cadia' provides a more in-depth and interconnected plot, lots of world-building within the story, passing goes at a reasonable speed, and its characters are way more interesting from the amount and diversity, giving a great amount of drama for a war story. Suppose there is one reason 'Fall of Cadia' feels like the best book on an imperial battle since Helsreach. In that case, it is because it puts character development and uniqueness first and uses the conflict to push them to the edge, providing great lines of dialogue, monologues and, best of all, memorable scenes that feel either out of an HBO drama or historical epic.
