So I've spent the last few years working on a novel. Don't know if I'll ever sell it, but I think about the main character, Emi, a lot. You spend that much time with a person--even a not real person--and it's hard not to wonder what she's up to when she's out of eyeshot.
I often feel this way about my characters. After I finished writing The Shadow Brothers (a billion years ago) Ken Cannon and I spent some time on the Navajo reservation, and I said to him, "I wonder if Henry will be happy here." And Ken Cannon said, "Henry? As in the fictional boy in your fictional story fictionally called The Shadow Brothers?"
He was alarmed, don't you know.
And who can blame him?
