This was cool. There's an AI, a human - AI relationship, sci-fi sounding scenes of something going on in space... The story makes you puzzle together what's going on, and that feels pretty nice too. Even though it might be that there are actually holes in the puzzle, at the time of reading I didn't notice it because it felt like it might get filled in a bit later.
Another interesting to me bit was that the protagonist is a woman, but it's not very relevant, and I was surprised when I noticed her referring to herself more than once during the book. I thought if I found out a protagonist was a woman I'd identify more with her and would find it easy to remember that she's not a dude.
Fun read.
