Yes, it's ridiculous.
But it's a good ridiculous, and Novik does just enough hand-waving to let us all know that she knows it's ridiculous, and if you don't mind, we'd all like to get back to the dragons now, please.
Because there's this evil albino Oriental mastermind dragon (er, mistress-mind, it's a girl dragon) who has joined Napoleon's side to teach him the ancient Chinese art of combined-arms air-land maneuver battle, and things look grim indeed for Our Side at the end of Book Three.
The really annoying thing about this is that, if you're me, you suddenly have about a million great ideas for historical fiction (or game products) with dragons in, and now you can't really use them because you'll look like you're just copying Naomi Novik, which indeed you are.
I hope the books sell in their millions; Novik has truly hit the sweet spot between lame and recondite where All Is Forgiven.
