Lady of the house Octavia Cavendish lives like a bird in a gilded cage. With her family’s fortune, her husband, William, has made significant additions to the estate, but he too feels bound---by the obligations of his title as well as his vows. Their son, Harry, is expected to follow in his footsteps, but the boy has dreams of his own, like pursuing the new adventure of aerial flight. Meanwhile, below stairs, a housemaid named Emily holds a secret that could undo the Cavendish name.
