There is not much of the plot of this book that anybody can talk about without spoiling it. What I can say is that it was wonderfully crafted to reveal little bits and pieces of the mystery along the way. Most importantly, the world building was sustained throughout the whole book! When the romance popped up I was a bit anxious that it would take over everything, but Taylor struck a really good balance of all the elements and made sure the angsty romance didn't distract from developing the characters, story and world. 
 Also: THE WORLD! I love love love the world. Built into it was a really great cast of supporting characters, who were all interesting and had their own relationships and personalities, and everything felt so rich and real as a result. 
 My only drawbacks would be that the romance was a bit unrealistic at times (but I can forgive that trope since there were other aspects of the story I could focus on) and that there was a pretty major shift in style near the end of the novel which could have been paced a little bit better - though ultimately it was probably ideal set up for the second novel. 
 A well written young adult urban fantasy with an angsty romance on the side -- what more do you want?! Looking forward to seeing how this story plays out in the rest of the books.
