A good ending, but... 
 Depressing. Usually, I can handle tough endings. Walk away from it in search of thoughts that eventually lift my feelings. In fact, I prefer books that demand an emotional response. I suppose it's all in the subject matter, and what I'm left with. Just give me some hope to build on. 
 I'm not saying that everyone will finish with the same feeling. We all read and take away what we will. Here is the plus I experienced: Distinctive (meaning original), and atmospheric. I can't remember reading a book displayed quite like this. It has a very much "in your head" style (Or should I say "in her head" - read the book and you'll understand). Do you like questions? This could work for you because many are asked along the way. Hints are dropped, but be prepared because now you may be the one asking the questions. By the half-way mark, if you're like me, you'll ask just what the blank is going on here. I'm okay with that sort of thing, mostly. Thankfully, answers are provided in the end. Whether the answers work for you, I could not guess.
