His Majesty's Dragon by Naomi Novik
Page: N/A (Finished it yesterday)

Aerial combat brings a thrilling new dimension to the Napoleonic Wars as valiant warriors rise to Britain's defense by taking to the skies...not aboard aircraft but atop the mighty backs of fighting dragons.

When HMS Reliant captures a French frigate and seizes its precious cargo, an unhatched dragon egg, fate sweeps Capt. Will Laurence from his seafaring life into an uncertain future--and an unexpected kinship with a most extraordinary creature. Thrust into the rarefied world of the Aerial Corps as master of the dragon Temeraire, he will face a crash course in the daring tactics of airborne battle. For as France's own dragon-borne forces rally to breach British soil in Bonaparte's boldest gambit, Laurence and Temeraire must soar into their own baptism of fire.

Now these are dragons. Easily one of the best novels involving dragons I've ever read. So much so that I immediately ordered the next two books of the series and am seriously considering preordering #4, which won't be out for a few months yet. Very highly recommended to anyone who likes dragons and alternate histories.
