From Blood Promise:
"The door opened, and it was like an apparition materializing before me, some sort of heavenly messenger descended from above. I'd never been away from her for this long, and after all this time, part of me wondered if I was imagining this.
He hand went to her mouth, and she stared at me wide-eyed. I think she felt the same way - and she hadn't even had warning of my visit. She'd just been told I was coming "soon." No doubt I seemed like a phantom to her, too."
