The Befanini family rules the kitchens of the de Medici and their allies, serving well by fortifying their patrons' reputations and influence with all the power that a brilliant meal can supply. Young Ginevra Befanini serves more directly as companion and confidante to Caterina de Medici, while Ginevra's brother Tommaso is learning his family's craft and enhancing it with his own ideas and talents. The political forces of Renaissance Florence pull and push at them; plague stalks them; and other alien forces move through the kitchens and the city, menacing Caterina and her friends.
