Can you recommend some unofficial Warhammer 40K Doujin novels?

Sure. 'Horus Rising' is a great one. It sets the stage for a lot of the major events in the Warhammer 40k universe. Another is 'Gaunt's Ghosts: First and Only' which follows the story of Colonel - Commissar Ibram Gaunt and his regiment. And 'Eisenhorn' is also quite popular as it delves into the life of an Inquisitor.

Sure. 'Double Eagle' is a great one. It has an interesting story about fighter pilots in the Warhammer 40k universe. Another excellent choice is 'The Beast Arises' series which is about a new threat rising against the Imperium.

Another good one is 'The Horus Heresy' series. It delves deep into the events that led to the great schism in the Imperium, with detailed art and complex storylines that are really engaging for fans of the Warhammer 40k universe.

I'd also recommend 'Double Eagle'. It's about the Imperial Navy pilots. It has a lot of exciting aerial combat scenes and is a good way to get into the different aspects of the Warhammer 40k world without getting too bogged down in complex lore right away.

Sure. One of the notable ones is 'The Horus Heresy' series which has elements of crime within the complex Warhammer 40k universe. It delves into the betrayals and dark secrets that can be considered as crimes in the context of that world.

, I recommend a doujinshi novel about AngelBeats to you. The title is "From the Battle of the Mighty Soldiers to the Nuclear World." This novel was based on the Divine College, a comprehensive manga world + a multiverse. The worlds involved included Diga, Godzilla, Overwatch, The Reunion, Pacific Rim, and so on. Although it's not based on AngelBeats, the content that involves AngelBeats might meet your needs. I hope you will like my recommendation. If you have any more needs, feel free to tell me. Muah ~😗

For beginners, 'Horus Rising' is a great start. It's easy to follow and gives a good introduction to the main concepts like the Space Marines and the early signs of the Horus Heresy. Another good one is 'Ciaphas Cain: Hero of the Imperium'. As I mentioned before, it has a more humorous tone which can make it easier for new readers to get into the complex Warhammer 40k universe.

One great Warhammer 40k Imperial Guard novel is 'Gaunt's Ghosts' series. It follows the adventures of Colonel - Commissar Ibram Gaunt and his Tanith First and Only regiment. The series is full of intense battles, great character development, and it really gives you a feel for the life and struggles of the Imperial Guard.

Sure. 'Horus Rising' is a great one. It sets the stage for a lot of the events in the Warhammer 40k universe. It gives you a good look at the Space Marines and the beginnings of the Horus Heresy.
