On the brink of war, one secret will tear a powerful family apart.
The Hartford sisters gather for one final night at Bonsall Hall, their once-grand family estate, on the eve of it being lost forever. The dinner is meant to mark an ending — a farewell to the house, the past, and the life they once knew. But before morning comes, everything changes.
Audrey, the youngest, is reckless and curious, always pushing against the rules that bind her. Katherine, the eldest, is controlled and calculating, fiercely protective of the family's reputation at any cost. Beatrice clings to elegance and influence through her dangerous political connections, while Sophia's radical beliefs place her on the opposite side of everything the family stands for.
When a guest disappears under suspicious circumstances, the fragile balance between the sisters begins to fracture. As Europe edges closer to war, their personal loyalties collide with their political convictions, and Audrey is drawn into a shadowy world of secrets, surveillance and power struggles that reach from country houses to intelligence offices.
With Britain racing to prepare for a conflict, the sisters must decide where they stand — with each other, with their country, or with their own beliefs. Because some truths could change the course of history… and some are deadly enough to destroy a family.
Of Sisters and Spitfires is a gripping historical thriller about family and the moral compromises made in the shadow of war, perfect for fans of Kate Atkinson and Robert Harris.
