Maybe "never" is too strong, but I'm not going to go out of my way to finish it in the near future. 
 Not because the writing was bad; on the contrary, it was very well written and had a fascinating, broken world (think a clockpunk/steampunk version of Gormenghast with heaps of suffering). 
 But it was pretty dark and dysptopic with rather unloveable characters. Which by itself I normally can handle, though it's a bit distancing. There was a very strong, strong emphasis of describing the world that the author built. Which is also fine, but again, puts another hurdle to becoming emotionally invested in the characters, because it ends up becoming more of a bigger story of the world rather than a story of certain people. 
 So I was mainly reading it for the plot, since I couldn't really care too much for any of the characters. 
 Third factor: while I tend to glaze over a little when the author goes on another tangent on the messy, stinking, ramshackle, and mutated outgrowth that is the city, he is very good at describing organic things. One of his most interesting and effective concepts is the idea of Remade humans/creatures, as a form of punishment or just because. But once he got to the red-light district, and described the "people" there....the imagery got stuck in my head for days. Not pleasant. 
 So if that type of thing is for you, then you'll be in for an absorbing read. Otherwise, stay away?
