I'm writing for my ideal reader, for somebody who's willing to take the time, who's willing to get lost in a new world, who's willing to do their part. But then I have to do my part and give them a sound and a voice that they believe in enough to keep going.

The evenings grew longer; kitchen windows stayed open after dinner and peepers could be heard in the marsh. Isabelle, stepping out to sweep her porch steps, felt absolutely certain that some wonderful change was arriving in her life. The strength of this belief was puzzling; what she was feeling, she decided, was really the presence of God.

The key to contentment was to never ask why; she had learned that long ago.

And yet, standing behind her son, waiting for the traffic light change, she remembered how in the midst of it all there had been a time when she'd felt a loneliness so deep that once, not so many years ago, having a cavity filled, the dentist's gentle turning of her chin with his soft fingers had felt to her like a tender kindness of almost excruciating depth, and she had swallowed with a groan of longing, tears springing to her eyes.

There were days - she could remember this - when Henry would hold her hand as they walked home, middle-aged people, in their prime. Had they known at these moments to be quietly joyful? Most likely not. People mostly did not know enough when they were living life that they were living it. But she had that memory now, of something healthy and pure.

It's tremendously hard work. Yes, I love arranging the words and having them fall on the ear the right way and you know you're not quite there and you're redoing it and redoing it and there's a wonderful thrill to it. But it is hard.

I have to pay attention to what I have felt and observed, then push these responses to an extreme while keeping the story within the realm of being psychologically and emotionally true.
