The Basics 
 Intriguing and unique in a YA genre where there are way to many fairy tale retellings. Good writing, great premise, but a bit more development would be nice.

 Full Opinions 
 For the most part I really liked this book. It was a quirky original idea that didn't totally fall apart. I read more than 100 pages in a day, which is a good sign, and, especially on the fairy-tale-retelling-adjusted scale, this one does its job and more. The Asian setting was a nice alternative to typical futuristic books set in America. The moon people thing seemed a little improbable but this book was not meant to be that kind of future book. It is complained that this book's a bit slow, but I prefer slow books to those Philip Pullman types where it moves at a "heart-pounding pace," that's too fast to follow. Despite having multiple subplots, the book was pretty clear. 
 However, I honestly expected a bit more than what it gave me. 
 First of all, the big reveal at the end is way too obvious. I think they should have just not revealed it until a necessary time and the hints weren't vague enough. I also felt a bit unsure over the names because it's set in China and Kaito and Rikan sound more Japanese. Adri seems European, while Torin and Garan sound like people out of some classic wizards-and- dragons fantasy. The writing also seemed a bit clunky at points and maybe the slightest bit kiddish. Lastly there were two more things that prevented me from giving this five stars. Firstly, I get this is a fairy-tale retelling but Peony and Queen Levana seem a bit more two-dimensional than they should be. Peony is immature and childish for her supposed age, while Levana is just basically a stereotypical villain, though a bit more distanced from the main plot. 
 Lastly, I can't really explain why, but I just didn't exactly like the ball scene. 
 I will be reading the sequels.
