Eh... to be completely honest, this book fell short for me. The premise sounded amazing, and the cover was gorgeous but I was really disappointed with character development, and just the general direction of the storyline. I'd give it a 2.5, because it wasn't throw-out-the-window-burn-it-with-fire horrible and I can see how this would appeal to a certain audience but I was hoping for a different sort of tale. The "resolution" between Hazel and Ben felt really weak, as well as between Hazel and their parents, and with Hazel and Jack. The lead up to this mysterious and compelling horned boy in the glass coffin fell flat for me because I didn't think Severin was interesting in the least. I feel like, based on the blurb, Severin should have been much more involved with the entire story - or at least have much more to do with Hazel. And I would have liked to have more shown about night Hazel, because being largely told about night Hazel rather than shown makes the ending feel rushed and quickly sewn together. 
 A good book, for me, leaves me wanting more. I did not want more after reading this book. I didn't regret reading it, but I don't want to hug it or force my closest book buddies to read it. I think I felt most frustrated because I expected something I didn't get, and what I did get was not spectacularly thrilling.
