But Venice is under siege by the Egyptian Empire; its terrifying mummy warriors are waiting to strike. All that protects the Venetians is the Flowing Queen. Nobody knows who or what she is—only that her power flows through the canals and keeps the Egyptians at bay.
When Merle and Serafin overhear a plot to capture the Flowing Queen, they are catapulted into desperate danger. They must do everything they can to rescue the Queen and save the city—even if it means getting help from the Ancient Traitor himself.
