Raised within the gloomy walls of the Chateau de Bieuvre, Yseult d’Arminge knows little of affection until a brief, sun-drenched summer with her cousin Jacques.

When the truth of Jacques’s devotion is finally revealed amidst the wedding fête’s cruel splendor, Yseult faces a heartbreaking choice between a sacred vow and the only love she has ever known.
