League of Dragons brings the Temeraire series to a fitting conclusion. The story picks up right where Blood of Tyrants left off: with Napoleon retreating to the west through the Russian winter. Novik captures the terrible pity of that march, the unrelenting cold of the borderlands, and the folly of men who tried to carry off so much treasure that they skimped on the clothing that survival required. In this volume, Novik finally begins to play around with European history, having air transport of French troops speed the retreat somewhat, and alleviate the deadliness of the river crossings that killed so many soldiers in our timeline. Allied commanders are also anxious to capture Napoleon because they believe that if he escapes, his dragons will transport much of the French army back to areas where they can be supplied and readied for a fresh spring offensive.
As with Blood of Tyrants, I found the section of League of Dragons set in Russia the strongest part of the book. The cold is palpable, the hardships of the men and dragons give meaning to the action, and the supporting cast is full of strong personalities. Again there are echoes of War and Peace, and other Russian literature. All of that adds up to show that Novik can write more than just a cracking good adventure when that is what she wants to do. The amnesia-driven realignment of Laurence’s personality even gets put to dramatic use: he compels a duel with a Russian nobleman. Aviators, in Temeraire’s world, are forbidden duels of honor because in the event of a loss their dragon might also be lost to the Corps. In early 19th century society, they are, for good and for ill, outside the realm of honor that still means so much among Europe’s rulers. Laurence, as a naval officer, was firmly within that realm, and he calls a Russian nobleman out by returning an unforgivable insult before anyone thinks to impress upon him what a bad idea that would be.
The duel is one of the best scenes in the book. The details, the things left unsaid, the competing agendas of the protagonists and seconds, with several different nationalities involved, make for gripping drama. The aftermath is nearly as good, with Temeraire wondering where Laurence has been gone so long, and the increasingly uneasy crew trying to conceal what their captain has been up to from a dragon who knows very well why duelling is forbidden among aviators.
