Following their mother’s accident, Clara and Stephen are sent to stay with their aunt and uncle. It’s a summer to explore the remote house, the walled garden and woods. Beyond it all the loch sits, silent and waiting. Auntie has wanted them for so long - real children with hair to brush and arms to slip into the clothes made just for them. All those hours washing, polishing, preparing beds and pickling fruit and now Clara and Stephen are here, like a miracle, on her doorstep. But as they explore their new home, the children uncover ghosts Auntie buried long ago. As their worlds collide, Clara and Auntie struggle for control. And every day they spend there, Clara can feel unknown forces changing her brother. Haunted and bewildered, this hastily formed family begins to tear itself apart.
