When Grace goes looking for the Traverses’ summer house, in the Ottawa Valley, it has been many years since she was in that part of the country. And, of course, things have changed. Highway 7 now avoids towns that it used to go right through, and it goes straight in places where, as she remembers, there used to be curves. This part of the Canadian Shield has many small lakes, which most maps have no room to identify. Even when she locates Sabot Lake, or thinks she has, there seem to be too many roads leading into it from the county road, and then, when she chooses one, too many paved roads crossing it, all with names that she does not recall. In fact, there were no street names when she was here, more than forty years ago. There was no pavement, either—just one dirt road running toward the lake, then another running rather haphazardly along the lake’s edge.
