My first job was in a nursing home - a terrible place in retrospect. It was in an old house, and the residents were so lonely. People rarely visited them. I only stayed there a couple of months, but it made a strong impression on me.
I love 'Memory Keeper's Daughter,' but in some ways I think 'The Lake of Dreams' is a stronger book. I was able to tell the story I wanted to tell. That's all you can ever do as a writer. From there on you have no control over it.
