The stunning, evocative and twisty new novel from the author of the Sunday Times bestseller and Richard and Judy Pick The Glass House

Kat, Flossie and Lauren are half-sisters who share a famous artist father - and a terrible secret.

Over the years they've grown into wildly different lives. But an invitation to Rock Point, the Cornish cliff house where they once sat for their father's most celebrated painting, Girls with Birdcage, reunites them.

Rock Point is a beautiful, windswept place, thick with secrets, electrically charged with the one subject the family daren't discuss. And there is someone in the shadows watching their every move. Someone who remembers the girls in the painting. What they did.

The sisters must unlock the truth to set themselves free - and find each other again.
