This is one of those situations where I start wondering if I read a different book than everyone else did. Or if I just missed out on something that everyone else caught onto within the story. Because I was so confident that I was going to love this read. SO confident. But I just ended up reading to finish rather than out of any degree of interest or enjoyment. 

The one thing I really loved without fail was the worldbuilding. I constantly wanted to know more about the alterations, the titans, the class system. There was so much to take in and I couldn't get enough of it. 
I was also especially interested in our main character, Din. He's quirky and likeable and just about the only character that felt fully fleshed out. We got peeks into his romantic life, his relationships with his family, his motivations concerning his career - he's a character that's easy to feel close to. Unfortunately, he was pretty much the only one I really cared about. 

Everything else about the book just felt like background noise. Like the kind of story that keeps the reader at a distance to enhance the mystery, but instead just prevents becoming fully invested. It's not that I disliked the other characters or the story itself - I just didn't care at all. I didn't feel strongly one way or another. I didn't feel close to any of the characters. I wasn't especially engaged in the mystery element. I wasn't captivated by the Sherlockish revelations that kept enlightening us while we trailed along one step behind. 

There's not much more to say. Tons of early reviewers loved this book and I hope most readers will. I wish I had been one of them because this felt right up my alley until suddenly it wasn't. 

Special thanks to Del Rey for an ARC in exchange for review.
