Naomi Novik’s beloved series returns, with Capt. Will Laurence and his fighting dragon Temeraire once again taking to the air against the broadsides of Napoleon’s forces and the friendly—and sometimes not-so-friendly—fire of British soldiers and politicians who continue to suspect them of divided loyalties, if not outright treason.

Laurence and Temeraire—joined by the egotistical fire-breather Iskierka and the still-growing Kulingile, who has already surpassed Temeraire in size—embark for Brazil, only to meet with a string of unmitigated disasters that leave the dragons and their human friends forced to make an unexpected landing in the hostile territory of the Inca empire, where they face new unanticipated dangers.

Now with the success of the mission balanced on a razor’s edge, and failure looking more likely by the minute, the unexpected arrival of an old enemy will tip the scales toward ruin. Yet even in the midst of disaster, opportunity may lurk—for one bold enough to grasp it.
