Well, 'Malus Darkblade: The Daemon's Curse' is also a great choice. It focuses on a very interesting anti - hero. The novel dives deep into the dark and complex world of Warhammer, with Malus having to face all sorts of challenges that are both physical and moral.
I'd recommend 'Horus Rising'. It gives a great introduction to the complex universe, with interesting characters and a plot that sets the stage for many of the events in the Warhammer 40K lore. Another good one is 'Gaunt's Ghosts: First and Only'. It follows the story of a regiment in a very engaging way.
I would recommend 'The Horus Heresy: Horus Rising' as a great novel to start with. It gives a lot of background on the Warhammer 40,000 universe and the events that led to the great heresy. It has engaging characters like Horus himself, and it really sets the tone for the epic scale of the setting.
Another great one to start with is 'Lords of the Sith'. It's not strictly a 'Rebels' novel but it has elements that tie into the Rebels storyline. It shows the relationship between the Sith Lords and the Empire, which is important background knowledge for understanding what the Rebels are fighting against.
I'd recommend 'Horus Rising' as a great one to start with. It's the first book in the Horus Heresy series which is a huge and important part of the Warhammer 40k lore. It gives you a good introduction to the Space Marines, the Imperium, and the main characters like Horus. You get to see the events that start the whole downward spiral for the Imperium.
They expand on the characters. Each hero has their own story, and these novels show how they fit into the greater Warhammer world. For example, a hero's origin story might explain certain aspects of a region or race in the lore.
One great one to start with could be 'Soul Hunter'. It really delves into the dark and brutal nature of the Night Lords. It gives you a good sense of their culture and how they operate within the Warhammer 40K universe.
Some of the best include 'Horus Rising' which gives great insights into the Horus Heresy. It sets the stage well for the epic conflict that unfolds.
One of the best is 'Horus Rising' by Dan Abnett. It sets up the Horus Heresy series really well, with great character development and an exciting plot that draws you into the dark and complex Warhammer 40,000 universe.
Some of the best Warhammer novels include 'Horus Rising' which is a great start to the Horus Heresy series, delving into the fall of Horus. Another one is 'Eisenhorn' which follows the story of an Inquisitor. 'Gaunt's Ghosts' series is also highly regarded as it shows the story of the Tanith First and Only regiment.
Definitely 'The First Heretic' by Aaron Dembski - Bowden. It gives a fascinating look at the Word Bearers legion before they fully turned to Chaos. It delves deep into their motives, the politics within the legion, and how the seeds of heresy were sown. It's a really in - depth exploration of one of the most important aspects of the Warhammer 40000 lore.
