I was thinking that since /t/bookclub exists and talks about novels monthly, Warhammer 40k fans would like to start their own thing. 40k has a ton of novels and audio books to choose from, so it's not like we'll have a meager collection to choose from. My idea for how this will play out is that if this post gets enough feedback, I'll start organizing people so we can start our own book club here in /t/books! It would be much like /t/bookclub, with the only difference being we'd only use Warhammer 40k novels.
For non-fans and people looking to get into this, I will help you out personally if you want to give you text to read (mostly from the wiki) that will give you a nice little intro into the grimdark future of mankind. A few basics: Praise the Emperor, praise the Emperor, and praise the Emperor. That's all, Imperial citizen!
Here are a few novels for you guys to mull over while we get it all set up:
Space Marine by Ian Watson
Space Hulk by Gav Thorpe
Assault on Black Reach by Nick Kyme
