At nineteen, Sebastian is a duke and heir to a vast country estate. A deep sense of tradition binds him to his inheritance, though he loathes the social circus he is a part of. Deception, infidelity and greed hide beneath the glittering surface of good manners. Among the guests at a lavish party are two people who will change Sebastian's life: Lady Roehampton, who will initiate him in the art of love; and Leonard Anquetil, a polar explorer who will lead Sebastian and his free-spirited sister Viola to question their destiny.
