I can't get enough of the 40k selection on the Black Library. Right now I'm working on reading through the Horus Heresy series, I'm starting on book 11, Fallen Angels, tomorrow. What I like about the Horus Heresy series is that it's not just point A to point B to point C. While the first four books act as a prologue and introduction to the opening moves of the heresy, later novels describe parallel events occurring during this time period, or sometime within the couple of centuries prior to Horus' betrayal. But what appeals to me most is that it doesn't focus on the primarchs; while they do occasionally take the main stage for a good bit of a book or two (primarily Fulgrim in his titular novel), most of the books focus on either sergeants or captains of the Astartes legions, or Remembrancers dispatched to the various Astartes fleets to record and memorialize the Astartes' triumphs. Aside from Horus Heresy I've read a good bit of Imperial Guard novels, including Ciaphas Cain and Gaunt's Ghosts. A good start book for IG I would suggest is Fifteen Hours. It's less than 200 pages, making it a relatively quick read, but captured the fatalistic mentality of Imperial Guardsmen stuck fighting an endless war on a planet they are sure to die on. The author I've read the most of would probably be Dan Abnett. My main issue with him is that his battle scenes can be a bit repetitive at times; this is mainly due to the fact that the majority of his works in 40k involve human-vs-human conflicts (Space Marine or Imperial Guard vs. Chaos Marines, Chaos cultists, or generic rebellions), and you can probably count on one hand how many of his novels involve xenos significantly. There's only so many ways you can describe someone firing a lasgun. Other than him, Graham McNeill is a name I tend to see a lot of. So what's your favorite books to read in 40k? Any you can recommend? I'd like to read a xenos-centered one if it's good (who am I kidding, they're all good).
