This book was really interesting. The premise was new to me and quite fascinating and the progression (transformation?) of the main character was interesting.
The author made a lot of subtle and not so subtle commentary about the dream to live forever and about way way advantaged people treat disadvantaged people (pitying them, but still acting as though they're expendable).
The one thing I didn't like was the last chapter. It was more of an epilogue and, save for exposing one key connection between two characters, it felt a bit gratuitous. Worse, it felt a little out of place and ruined the beauty of the last scene.
All that said, it's a good book and worth the read.
