Nemesis is a diabolic, meaning she was created for a specific purpose - to kill. Nemesis is the diabolic for Sidonia, a Senator's daughter and when the Senator annoys the Emperor, he sends for Sidonia to join him at the Grandiloquy. Knowing this means putting Sidona in mortal danger, her parents sent Nemesis instead, disguised as Sidonia. Now Nemesis has to be the opposite of what she was brought up to be, and is all alone on the other side of the universe.

I've seen this book floating around a bit and didn't really know what I was getting into when I decided to grab it from the library but i was pleasantly surprised. This was quite an elaborate sci-fi world and while it is confusing at first (and would be for people not used to sci-fi), it's easy to start getting along with after a while. It could probably have done with slightly more world-building but I was happy enough with what we got and what Nemesis explained.

Nemesis was fantastic as a character and goes through tremendous growth, while still staying 'true' to herself along the way. She is smart and strong while also being decent, kind and compassionate. The friendships she forms away from Sidonia are lovely to watch, and her friendship with Sidonia is also great.

The ending was really neat which was disappointing as I would love another book (or maybe even a standalone sequel based in the same world). I was happy with Nemesis's journey and where she ended up.
