It's a grimdark space opera, I guess? Blended with cosmic body horror and gritty cop story. With the R-rating soup that's common to modern sci-fi. 

There's a "good" ending, but it takes a lot of excessive violence, cursing, sexual topics, cynicism, moral ambiguity, etc to get there. There were funny parts, and it was very well-written, but it's not my favorite thing. There aren't really any noble characters (I think it says there are, but they're super flawed). 

Hard to gauge pace, because there were times of nonstop action, but also some slow portions.
