After their fateful adventure in China, Captain Will Laurence of His Majesty’s Aerial Corps and his extraordinary dragon, Temeraire, are waylaid by a mysterious envoy bearing urgent new orders from Britain. Three valuable dragon eggs have been purchased from the Ottoman Empire, and Laurence and Temeraire must detour to Istanbul to escort the precious cargo back to England. Time is of the essence if the eggs are to be home before hatching. Yet disaster threatens the mission at every turn, thanks to the diabolical machinations of the Chinese dragon Lien, who blames Temeraire for her master’s death and vows to ally herself with Napoleon and take vengeance. Then, faced with shattering betrayal in an unexpected place, Laurence, Temeraire, and their squad must launch a daring offensive. But what chance do they have against the massed forces of Bonaparte’s implacable army?
