I thought this book was fine, just maybe not entirely for me. I did have some issues with pacing, tone, and character; the chapters are so long which may make you think that you'd get a good grip on all the different characters but I felt that the individual voices were fairly indistinct (but maybe this had to do with what I felt to be overall a plain tone/writing style in the story). Another issue I had was that things would be explained over and over again, often back to back, as character POVs switched and characters learned the same things we the reader have already learned again and again. It also kind of dragged right up until the very end which read, to me, like a big confusing mess. All these random objects and "magical" things popped up throughout the story and I was told that these things were important, but they never felt that way. Everything kind of just happened one after the other, nothing to me felt like it had weight in the story. 
I did like the scary moments and monster descriptions (especially Walter, absolutely horrific in the best way) and I thought the setting was interesting, I just wanted more impact from everything overall.
