I loved this book. I loved the world that it took place in because I could imagine it so well. The violence and chaos of this world finally ripping something dark open and letting all the monsters in. I liked learning about the monsters, the legends and rumors surrounding them, their appearance, their weaknesses. 
 I loved Kate and August. Kate, a girl trying to be a monster and August, a monster trying to be a boy. Their friendship was odd, but so endearing. They were both trying to impress people in different ways and trying to survive this crazy world as best as they could. 
 The surprises and twists were shocking. Even in the last few pages, there were more to come. 
 My favorite element of the book was the level of action and violence. I mean, it's a world full of monsters, humans and creatures alike, so there was plenty of fighting, running for your life, and nail biting moments. I can't even tell you how many times I audibly gasped while reading this book, hoping the characters would make it out with their lives, let alone all their limbs. 
 Definitely going to read the next part of this story.
