Good? I guess I'm just not a fan of it like others seem to be. I personally found it lacking. The premise itself was pretty interesting, asking us question what exactly makes us human. The writing was great as well. However, I found a couple flaws. First, the book just kind of screamed to me UGLIESUGLIESGLIES. Despite the different premise, the technology/setting/lingo just reminded me of the Uglies series. Also, the major flaw was the female protagonist. I found her annoying, dull, and whiney for most of the book (though she did get better). I guess I should be more understanding since she's in a pretty sucky situation, but because the book was in her POV, I'd prefer her as a more kick-butt heroine, instead of moping around.
