League of Dragons is the ninth and final novel in the Temeraire alternate history/fantasy series by American author Naomi Novik.

While the emperor regroups, the allies have an opportunity to strike first and defeat him once and for all—if internal struggles and petty squabbles don’t tear them apart.

Aware of his weakened position, Napoleon has promised the dragons of every country—and the ferals, loyal only to themselves—vast new rights and powers if they fight under his banner.

Reviewing the novel for NPR, writer Jason Heller stated: "League of Dragons masterfully wraps up so many plot threads and loose ends that had built up throughout the previous eight books".
