I'm not entirely sure as I haven't read it specifically. But generally, in the Warhammer 40k universe, novels often deal with themes like war, the struggle between different factions, and the harsh realities of that dark future. It might be about the loss of purity or naivete in the context of the 40k setting, perhaps following a character or group who experiences a shattering of their initial ideals.

Death in a Beautiful Manga was a novel written by Happy Fat Sausage. The general plot of the novel was as follows:
Sword Slayer, Ghost Path, Spirit Pressure. I've always wanted to write a novel about the Grim Reaper. I hope everyone will like it. Let's follow the settings of this book. This story is purely fictional. Any similarities are purely coincidental.
One main theme could be the danger of extreme mountaineering. K2 is extremely difficult to climb, and this book might focus on how the climbers put themselves in harm's way.
The Death Guard 40K novels are unique because of their focus on the theme of decay and corruption. They explore the twisted nature of the Death Guard, who are servants of Nurgle, the Chaos God of decay. This gives a very different feel compared to other 40K novels.
Since I haven't read the novel, I can't say for sure who the main characters are. However, in Warhammer 40k novels, there are often soldiers, psykers, or leaders. It could be a young Space Marine initiate whose innocence is tested, or a civilian caught in the crossfire of a planetary invasion.
I'm not entirely sure as there could be multiple main characters depending on the specific plot of the 'death world 40k novel'. But usually, there are soldiers or adventurers who are central to the story.
The 'Death or Glory 40k Novel' likely centers around the characters' quests for honor or victory in the brutal and unforgiving Warhammer 40,000 setting. It could feature Space Marines, Orks, or other races engaging in combat, with themes of sacrifice and heroism. Maybe a group of soldiers is faced with a seemingly impossible mission and they have to choose between certain death or achieving a great glory through their actions.
In the 'Death or Glory 40k Novel', the main characters could be a diverse group. There might be a young and inexperienced recruit who is eager to prove himself. There could also be a grizzled veteran who has seen countless battles and is now mentoring the newbies. Additionally, there may be a powerful psyker who uses their psychic abilities to aid their comrades in the fight against the enemies, whether they are Chaos forces, Tyranids or other threats in the Warhammer 40,000 universe.
One interesting aspect could be the unique and harsh environments depicted in the 'death world' concept. These worlds are often filled with extreme terrains and dangerous creatures. Another aspect might be the complex characters that have to survive in such a brutal setting.
One great Death Guard 40K novel is 'Plague War'. It really delves into the nature of the Death Guard, their grotesque and corrupted ways. It shows their battles and how they spread the plague across the galaxy in a very vivid and disturbing manner.
