Portland. A limestone island off the Dorset coast, tethered to England by a single road and a thread of pebble beach. Three prisons. Ancient quarries. Six hundred years of secrets buried in the rock.

In 1999, William Delaney arrives with his two daughters, fleeing a collapsed marriage and hoping the island's history might inspire a book. What none of them expect is the island to reach back.

In 1348, a sailor named Galfridus returns home to find the Black Death has come ashore before him — carried, perhaps, by his own ship's crew. As the plague moves through the community, something older and stranger moves with it.

Seven centuries apart, two families are pulled toward the same stone, the same crack in the earth, the same white-haired girl who will not stay dead.

Layered like the island's own geology — from Rubble on the surface down through Kimmeridge Clay to the Basal Shell Bed below — Light Come, Light Go is a novel about what the ground beneath us holds: the dead, the past, and the things that refuse to become either.

For readers of Sarah Waters, Andrew Michael Hurley, and Alan Garner.
