After defeating Napoleon's forces at the battle of Dover, Laurence and Temeraire are confronted by envoys from
Imperial China, including Prince Yongxing, brother of the
Jiaqing Emperor. The Chinese are eager to recover their rare Celestial dragon from the
British. According to Chinese law, Celestials are only allowed to accompany royalty; Temeraire was intended for Napoleon,
Emperor of the French, while Laurence, a mere commoner, is deemed unworthy. This raises consternation within Government, as a Napoleon allied with China—the most powerful nation in the world, isolationist and able to keep other countries at bay through their superior draconic husbandry—would be impossible to oppose. After several failed attempts to convince Laurence and the Royal Aerial Corps to return Temeraire to China, the Chinese and the British agree to have Temeraire and his flight crew — including Laurence — accompany the Imperial envoys back to China. As the land routes are deemed unsafe, the Navy has a dragon transport, HMS
Allegiance, captained by Laurence's former second officer Tom Riley, ferry the Celestial and his crew to China. During the voyage, attempts are made on the life of Laurence in order to remove him from Temeraire. In addition, political machinations on the part of the British,
French, and Chinese are discovered that threaten the position of Britain in the East, as well as the stability of the Chinese throne. News of the defeat of the
Third Coalition at the
Battle of Austerlitz and subsequent death of
Prime Minister William Pitt casts a pall over the voyage. Finally, Laurence has ongoing difficulties with both Captain Riley, a staunch supporter of the slave trade (Laurence himself descends from known abolitionists), and the diplomat Arthur Hammond, sent along to smooth the operation. During the sea voyage, Temeraire catches a respiratory illness from Volatilus, a slow-minded though sweet-natured Greyling serving in the courier corps who visits the
Allegiance with dispatches. They stop at
Cape Town, lately captured in the
Battle of Blaauwberg, to look for a remedy. By use of a
posset made using an extremely smelly
mushroom, the cooks of the Chinese delegation are able to restore Temeraire to health. This event, though seemingly unimportant at the moment, shapes the next two novels of the series. After their arrival in China, Temeraire gets to meet his family, including his mother, and observes the conditions of dragonkind in China, which he deems far superior to British custom: Chinese dragons are citizens in their own right who, amongst other things, may take the
Imperial Examination. He begins courting an Imperial dragon named Mei, and is exposed to a young boy of Yongxing's company, who attempts to befriend him. Laurence, for his part, attempts to learn Chinese, liaises with the French ambassador
de Guignes, and suffers more direct attempts on his life, including confrontations with Yongxing and his companion, the
albino Celestial Lien. Hammond is able to deduce that Yongxing has designs on Prince
Mianning, the heir-apparent whose dragon is Temeraire's twin brother, and that Temeraire was sent to France not because the Chinese esteem Napoleon—indeed, the British are relieved to learn that the Chinese have no particular esteem for Napoleon at all, laying their greatest fear to rest—but so that Temeraire himself could not be used to complicate the line of succession. Indeed, Yongxing has had him returned to China so that Temeraire may lend legitimacy to a
puppet king Yongxing intends to set upon the throne. At a theatre production in the British delegation's honor, Yongxing attempts to put his plans in motion. However, he is prevented by the actions of Temeraire and Laurence, and is himself killed in the ensuing scuffle. As a result, the Emperor of China himself adopts Laurence as an honorary son, at a stroke resolving the issues with Laurence's social status and easing relations with Britain. Temeraire, after much deliberation, decides to return to Britain, partially out of love for Laurence and partially to attempt to bring the greater civil liberties of the Middle Kingdom back to the
Commonwealth. ==Reception==
