Isolated on their private island in Cornwall, the Darker family have come together for the first time in over a decade. When the tide comes in, they'll be cut off from the rest of the world for eight hours. When the tide goes back out, nothing will ever be the same again. Nothing – because one of the family is a killer . . .

As the leaves of autumn fall, Daisy Darker arrives at her grandmother’s house for eightieth birthday celebrations. Seaglass, the Darker’s ancestral home, is a crumbling Cornish house perched upon its own tiny private island.

Every member of the family has their secrets. Nana, alone for so long. Daisy's absent father, Frank. Her cold-hearted mother, Nancy. Her siblings, Rose and Lily, and her niece, Trixie, full of questions and without a father of her own. Daisy has never had an easy relationship with her family, but some secrets are much darker than others. This will be a gathering that some of them won't remember.

'I was on the edge of my seat the whole time' – Taylor Jenkins Reid, author of Daisy Jones and the Six
