This is hands-down best thing I've read in a really really long time. I loved Ancillary Justice. I love the characters and the writing, but especially, I love the world-building. 
 I love the attention Leckie pays to the variances in culture and language in this future. I love the technology and the ships and the concepts and her vision of artificial intelligences is so unique, I just, ugh, love. I love the fact that everyone is assumed brown and female until otherwise mentioned. I love that it sort of simulates basically anyone who isn't a straight white man's experience in sci-fi, where you're given maybe one explicit representation of yourself, and if you want you have to dig and infer and read between the lines to find someone, anyone else who might resemble you, and then it turns out that they're the villain. 
 I love the frank examination of imperialism and the cold cruelty of a system that operates on socio-economic inequality and discrimination. I love that literally everyone in the novel is shown to be complicit in this system, regardless of their direct involvement or intent. 
 I even love the ending, like, how often do you read such an interesting story that then has a satisfying conclusion? Like the kind of ending that you wouldn't even mind being THE ending, it's just that satisfying. 
 And hell, even the things that might annoy me in other books, some writing bits and expositional dumps, I don't mind because everything is just so goddamned interesting, you could dump it in to an encyclopedia and I'd lap that shit up. 
 I love Ancillary Justice and you guys should all go pay money for it and read it right now.
