There's one reason only that this one did not get a full 5 star and that is because it's TOO DAMN SHORT. 
 I know Queen Levana is evil, this book does not attempt to change that however, I think Marissa Meyer created her most complex character yet when she penned this. Like many of her heroines Levana does not have a nice happy childhood. The difference is how it twists her into something evil. Was she going to be evil or is she a product of her environment? Perhaps her environment pushed that innate evilness. Either way we have a very twisted character, there's moments when you see and feel her humanity, she's layered, there's softness there but she keeps twisting it until malice surrounds her. 
 I loved it, loved every bit of it despite the lack of action like the rest of the Lunar books, following Levana through the decade that made her evil was a refreshing and in my opinion a far superior narrative.
