 The transformation protagonist undergoes from previous book to this, is jarring. It's definitely interesting as the plot ploughs forward at a steady rate. We are introduced to new characters while the old ones are reshaped and progress further. Sword is an expansion on Justice, works almost like volume two of the same book than a sequel. There isn't much new technology wise which works as a major plus point. The story concentrates on history and politics of the world which is complex with different races and species competing for same set of resources. 
 The protagonist, Breq, finds herself a steady growth through the pages and somewhere in the middle of this book, she earns compassion and become a being to be empathetic about. It doesn't matter that she is an AI as some of her actions are nothing less than humane. Thankfully this progression is timed in such a way that the story sheds few layers by offering clarity regarding imperialist regime. 
 The ending is quite rushed but that's okay. Its a touch and go situation which thankfully didn't drag. I am glad I picked it up as the continuing tale to Ancillary Justice was quite satisfying.
