The first time I ever saw Castaway House I knew it was meant to be mine …
Final cover image

It’s 1965 and eighteen year-old Rosie Churchill has run away to the beautiful but run-down Castaway House in the seaside town of Helmstone. But when she uncovers a scandal locked away in the walls of the old house, she soon comes to realise that neither her own troubled past nor that of the house will stay buried for long. . . In 1924 fresh-faced Robert Carver comes to Castaway House to spend a languid summer in the company of his much wealthier cousin, Alec Bray. But the Brays are a damaged family, with damaging secrets. And little does Robert know that his world is about to change for ever. As Rosie begins to learn more about Robert, the further she is drawn into the mysterious history of the house, and their stories, old and new, entwine.
