WELCOME TO ERIS - A TIDAL ISLAND WITH ONLY ONE HOUSE, ONE INHABITANT, ONE WAY OUT. . .

A place that is unreachable from the Scottish mainland for twelve hours each day.

Once the hideaway of Vanessa, a famous artist whose husband disappeared twenty years ago.

Now home to Grace. A solitary creature of the tides, content in her own isolation.

But when a human bone is uncovered in Vanessa's artwork, far away in London, Grace receives an unexpected visitor.

AND THE SECRETS OF ERIS THREATEN TO EMERGE. . .
