Olive Wellwood is a famous writer, interviewed with her children gathered at her knee. For each, she writes a private book, bound in its own colour and placed on a shelf. In their rambling house near Romney Marsh the children play in a storybook world - but their lives, and those of their rich cousins and friends, are already inscribed with mystery. Each family carries its own secrets.

Born at the end of the Victorian era and growing up in the golden summers of Edwardian times, a whole generation grew up unaware of the darkness ahead; in their innocence, they were betrayed unintentionally by the adults who loved them.
