I received and ARC of this book in exchange for an honest, unbiased review. 
 This book had its ups and downs for me. On one hand, I really enjoyed it, but on the other, it was just okay. I'm going to start with what I liked about the book because it's going to seem like I really didn't like this book after I write about the cons. 
 So pros: 
 The storyline and world is very imaginative and creative. The world that Ms. Lee has created is completely unique, and I found it extremely interesting. I wanted to learn so much more about it, but I'll talk about that later on. Ms. Lee's writing is also very well done. The scenes came alive, and were richly described. I was instantly transported to Ninurta. The world is very much fleshed out in the beginning. Because of this, the reader truly feels like they understand the world of Ninurta, almost as if they could navigate the streets if they were placed there the next day. I absolutely loved this! However, after we leave Ninurta, the world building just disappears, and the reader gets a bit confused at times. Avan's character was one that I enjoyed immensely. At first, I was a little wishy-washy in how I felt, but as soon as he has a much stronger presence in the novel, I grew to love him. He is extremely protective, and a true friend to Kai. I felt there were many times where Kai took advantage of his friendship, and is one of the many reasons I couldn't get into her character. I also liked G-10 (view spoiler)[who chooses the name Mason later on in the novel (hide spoiler)]. He had me cracking up, and I loved the way he pushed both Avan and Kai to become their strongest selves. 
 Now onto the cons (but bear with me): 
 My main problem with this book was Kai. I never could connect or get into her character. I felt at times she was strong, but then she went right back to being naive and too reliant on other characters to get through. Kai was very selfish at times, and there were many times when I wanted to slap her. She has her shining moments, but they are fleeting and weren't enough to get me to like her character overall. I also wished that her power to affect time was explored much more. From the description of this book, the reader is led to believe that her power will play a large role in the novel. It's not. It's mentioned a lot, but only in passing, and used a maximum of 5 times throughout the entire book. I understand that she doesn't understand her powers for the vast majority of the book, but I still would have liked a bit more, especially when the truth comes out. Plus, she didn't even seem to want to embrace these powers! Obviously, her powers will probably be explored much more in the next book, but I think it should have been more of a priority in this first book. Now onto my other major problem...a lot of the events that occurred in this novel were extremely random. The stored jumped around from one place to another, and it seemed like there was never really any rhyme or reason as to why they would do something. Even the explanations seemed random, or perhaps it would be better to say extremely convenient, at times. Don't even get me started on the mess that was the romance in this book. I thanked my lucky stars that there was no love triangle, but I didn't like how the romance was handled from the very beginning of this novel. And this feeling remained with me for the entire book. 
 The ending was just a mess in my opinion. I felt it was extremely rushed and was confusing. There was bombshell after bombshell being dropped on the reader, and it's not an enjoyable experience. I feel as if the ending is one in which you'll understand what I'm talking about once you read it, because it's hard to write about without giving away the entire ending. There were plot points that the author took and rewove into something else, only to backtrack a couple paragraphs later and create something entirely new. 
 I think this series has enormous potential, but I don't think I'll read the next book. Honestly, as much as I didn't like the ending, it ended in a way that was enough of a conclusion for me to be satisfied. I think that this book could have used a bit more work before publishing because then the story could have flowed much better. To some, I think this book will be right up their alley and it will be very enjoyable. They'll be able to look past some of the things, and want to read the next book. However, for me, it wasn't my cup of tea. I was very disappointed in this because I feel like this book could truly have been an amazing novel. It just wasn't quite there yet.
