DNF @ about 50% (?)

This book really hooked me from the beginning and although the writing felt something to be desired I could overlook it. I found the way that the characters conversed, although awkward and unrealistic, to really add to the overall weirdness and tension of the story. 

Things took a turn when the "twist" happens at the end of part 1, about 50% in the book. I will not spoil anything, but I found that this twist really changed the tone of the book in a way that made me lose interest completely. I actually went ahead and read spoilers of what happens next and I just found it completely uninteresting and reductive to what I was hoping was going to be a much more compelling story.
