This book was beautiful, yet so sad. 
 I was excited for this book because I had heard that it was inspired by the movie Labyrinth (which I have a strong fascination for). 
 I loved the world and the fact that the story was set in a historical period that existed in the past. I have a sweet spot in my heart for fantasy books set in our real world. I also adored the interaction and the relationship between Liesl and the Goblin King. 
 However this book, unfortunately, disappointed me in some aspects. First, the writing style was sometimes all over the place. We would go from a beautiful description to an average one. Also, the fact that the word "plain" was repeated over and over again in this book annoyed me (I don't like the cliche of the young girl/woman always comparing herself to others, it annoys me to no end). Also, I wished that this book was not young adult because there was some scenes in it that could have been more powerful if they didn't have to be censure. For example, the sex scenes in it were too similar to other YA sex scenes, they were just confusing and over the top. 
 Overall, I really enjoyed this book. Even if I was a little bit disappointed in the end, I would love to read more books from the author (and especially more books set in this world).
