Crucible of Gold (Temeraire #7)

Naomi Novik’s beloved series returns, with Captain 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.
 
For Laurence and Temeraire, put out to pasture in Australia, it seems their part in the war has come to an end just when they are needed most. But perhaps they are no longer alone in this opinion. Newly allied with the powerful African empire of the Tswana, the French have occupied Spain and brought revolution and bloodshed to Brazil, threatening Britain’s last desperate hope to defeat Napoleon.
