** spoiler alert ** 
 Well, this is a book about a rapist, a child abuser, a despot, a murderer and a genocidal tyrant with pathological narcissism. If you can deal with the fact that the book is written from that perspective, and that it will make you rather queasy to be in a rapist's head, it's not bad. 
 I did feel it was full of missed opportunities, however. It's the weakest showing the series. There was some backstory, and some dystopian technology, and some interesting moon factoids, and a sprinkling of politics, but it was mainly referencing things we already knew from the other books. This book would not stand on it's own if not for the others. I wish there were more in-depth politics, much more about how the moon's monarchy was created (and how it even started as a republic-- we get like one sentence only saying it was one), and a bunch of other things. Besides, I didn't feel like there was much character development. Levana really did not change much throughout the book, only the events and choices of the people around her seemed to bring out in her what was already within. From the beginning of the book she was jealous, vengeful, fantasized about murder, possessive, delusional, abusive, controlling, spiteful, and with a very limited emotional range. The difference was in the beginning she was not in a position of power, and we're introduced to her weaknesses and neuroses. 
 I can't say I was ever really sympathetic to her, despite her early childhood disfigurement and her embarrassment at the hands of her sister. Terrible things, but they can't account for all of her personality disorder. Her book-long pity party was not enough for me to love the novel; I just wish there had been more there about the other characters, how things on the moon got started, and being let into other parts of her end-game. 
 Then there were also little annoyances, like... they live on the moon, where they need oxygen badly, and they are putting out fires in the palace with buckets of water? They don't even have a sprinkler system? Or, by then, have a basic fire extinguish handy? Advanced chemical fire suppression foam? Fire hoses? Good lord. 
 Or the guard's minds being easily controlled for security reasons. I get this is a major plot point, but holy heck. The arrangements make no sense. Actually that's a great way to ensure that you're not really secure, if everyone on Luna except Shells have the ability to glamour people, and the guards don't have mental toughness and are easily manipulated. How is everyone not dead yet? Especially since even Levana doesn't have the energy to keep her glamour up all the time, much less control her guards all of the time, especially when she's sleeping. Sense: it makes none. 
 That said, I can't wait for Winter. I want Winter to kick Levana's ass and avenge her mother and father-- especially her father.
