One identity, many bodies
From a science fictional point of view, this series is an exploration of distributed identity: what does it mean for a single consciousness to inhabit many bodies, what are the psychological and ethical ramifications?
From a literary point of view, there are a couple of interesting techniques here. Since the narrator comes from a culture that does not distinguish gender in their language, all characters are referred to as 'she,' regardless of the character's physical sex. The reader will develop opinions about what sex various characters probably are, but it's never made explicit, and you may be forced to reevaluate your assumptions at some point.
Having many bodies with a single mind allows for an unusual First Person Omniscient style in parts of the story; the author clearly enjoyed playing with literary style this way.
This is an enjoyable read, a fairly straightforward Space Opera with a couple of SFnal and stylistic twists to keep you on your toes.
