From the back of the book:
"I was an angel.
I wasn’t an angel of vengeance, or an angel of mercy, or even an angel of death. I was an angel of the Machine. I came to Earth wrapped in a Cover that the Machine provided, and I served. Service didn’t make me happy, but it made me what I was. An angel.
But then I stopped serving. Why? It’s complicated. You were involved. That’s all I’ll say for now.
I stopped serving, and when I did, I Fell. And what does that make me?"
