From Inside the Grey House:
“Kill me.”
She pulled away, surprised, but kept her own voice quiet. “What?”
“Let me die a man. It’s what I am. Don’t let them change me. I don’t want that. My kid brother was changed into a vampire. I saw it happen. I don’t think I could stand it if I was changed.” He hung his head. “It’s probably why the angels never chose me. I don’t have the strength to be anything but me.”
She had no idea what he was talking about and needed to make sure she understood the agreement. “So you’ll tell me whatever it is you know and then I kill you?” She shook her head. “I don’t understand why you’re even trying to tell me anything.”
