Venice stands victorious. It has beaten back the German emperor’s army and the Byzantine navy. The Duchess Alexa’s party at court is strong again. Her niece, Lady Giulietta, will be the next Regent, and possibly the next duchess. Giulietta’s lover, Lord Tycho, will sit beside her. But no one is prepared for the fury of Prince Alonzo, exiled regent and traitor to his city. No one is prepared for the harshest winter Europe has ever known. As the canals of Venice freeze and wolves cross the ice from the north, Alonzo’s plotting brings the Venetian empire to the very edge of destruction. With the Millioni family at war with itself, Lord Tycho, once a slave and a trained assassin, has to ask himself the only question that matters. How much is he prepared to sacrifice to keep Lady Giulietta’s city safe?
