There are echoes of C.J. Cherryh, Iain Banks, and Frank Herbert in  Ancillary Justice.  The novel is both familiar and fresh.  The writing  is powerful and tense. The plot -- about which I will say little, lest I  risk spoiling it -- is intelligent and surprising.
The Radchaii  are human but they consider themselves superior to other humans. The  Lord of the Radch, Anaander Mianaai, controls Radch space with the help  of thousands of genetically identical, linked bodies. Extra bodies seem  handy (wish I had some) but they prove to have unforeseen consequences.  The Radch rule by conquest, annexing other human worlds and forcing  their inhabitants to join the Radch or to surrender their bodies to be  used as ancillaries, otherwise known as corpse soldiers (an ancient  practice that has been mostly abandoned). They justify their actions  with the belief that they are imposing order and justice on the  universe.  They control annexed planets by coopting the privileged  class, allowing them to retain their social status provided they embrace  the Radch.  The one exception is Garsedd, a planet the Radch destroyed  because the Garseddai posed a threat the Radch could not tolerate.
The  protagonist of Ancillary Justice, having been manufactured by the  Radchaai, is sometimes a ship called Justice of Toren, sometimes an  ancillary called One Esk, sometimes other ancillaries.  As the novel  begins, however, the protagonist is called Breq. All of those identities  should be the same, but Justice of Toren/One Esk/Breq is having an  identity crisis. No longer endowed with the abilities of an AI, Breq has  the weaknesses of a human ... without quite being human.  In the first  pages, Breq saves a Radchaai named Seivarden (who once served on Justice  of Toren) from hypothermia.  The story then alternates between the  present (Breq is tracking someone in order to obtain something ... more  than that I won't reveal) and a past in which One Esk was serving the  Radchaai, who had just used ruthless means to annex a planet called  Shis'urna.  The final element of the story is the Presger, a race of  aliens who once made pests of themselves by dismantling Radch ships.
The  novel's background is more intricate than I've sketched out here. It is  initially confusing ... but initial confusion caused by complexity is  better than boredom caused by pages of exposition.  Everything falls  into place well before the novel's midway point. Ann Leckie plays with  gender and culture in ways that are interesting but subtle. Her prose is  robust.
The story builds upon a familiar moral struggle --  whether to follow unjust orders if the penalty for disobedience is  death.  If doing the right thing will have dire personal consequences,  is it best to do the right thing only when it will make a difference?   And how does one know whether doing the right will make a difference?   These are difficult questions and Ancillary Justice brings them into  sharp focus in different ways.  More than one character, not all of them  human, must make a choice of that nature.  Ancillary Justice makes the  point that virtue is easy to achieve in the abstract but easily vanishes  when the lives of the "virtuous" are at stake.  It makes the equally  salient point that it is easy to judge when it isn't your life that is  at stake. At the same time, this isn't a preachy novel.  Leckie leaves  it to the reader to draw whatever lessons might be taken from it. The  blend of philosophy and adventure, the imaginative culture-building, and  the strong characters all add up to an impressive work of science  fiction.
