This is one of the first L&C fanfic I read, and remains one of my favorites. It's one I can read over and over, especially when I need uplifting. I'm one who needs to be in the right mood to read heavy angst, tragedy, etc. My preference remains positive, uplifting stories.
Margaret's introspection and conflict about contacting Clark and knowing his secret shows the burden those knowing carry. And it's nice to see how a stranger becomes a friend giving Clark support and encouragement during a painful lonely time.
