Isabel Boncassen arrives in England with her scholarly father, charming everyone from the Duke downward while refusing to be a suppliant for a coronet. She loves Silverbridge, but she will not force her way into a family that means to repudiate her — she must conquer them first, or not marry him at all. Her patient campaign to win Lady Mary's esteem, and the Duke's grave interview with his future daughter-in-law, put the novel's questions about blood, nation, and worth directly to the test.
