Any Orson Scott Card enthusiast who has tried out the audiobook versions will know that they are a wonderful way to access his work, as it is so dialogue based. This is a gem: so beautiful in its simplicity. I had tears running down my face for most of the train journey during which I listened to it, but didn't care: it's exquisitely sad and breathtakingly moving.
I'm a big OSC fan but this didn't seem as well written or involving as his other work. I'm sure many will find this uplifting, but I found it vaguely depressing.
