Lake Superior does not give anything back. Every soul on this shore knows it the way they know the ice and the wind. Then, on a still morning in the dead of winter, it gives back a boy. They find him in the shore ice below the Greenstone Light. Nineteen years old, lost with a fish tug in a November gale sixty-seven years ago, whole and unspoiled, as though the water set him down last night. The town calls it a wonder and puts it in the paper. Nell Korhonen knows a lake does not make that kind of mistake. She kept the light.

She is three months into learning what the keeping actually is, and what it costs a woman to read what stones remember on purpose instead of by accident. Now there are salvors out on the wreck for a dead man's estate, hurrying something she can already feel coming, and her mother's notebook has begun to give up the terms of a debt this family has been paying for a hundred years and more. A thing given back is a thing being asked after. The lake has never once collected from a stranger. It comes for the warm ones, and it comes before the ice goes out.
