"All's fair in love and war," according to airship captain Josette Dupre, until her hometown becomes occupied by the enemy and her mother a prisoner of war.

Then it becomes, "Nothing's fair except bombing those Vins to high hell."

Before she can rescue her town, however, Josette must manoeuvre her way through the nest of overstuffed vipers that make up the nation's military and royal leaders in order to drum up support. The foppish and mostly tolerated crew member Lord Bernat steps in to advise her, along with his very attractive older brother.

Between noble scheming, undertrained recruits, and supply shortages, Josette and the crew of the Mistral figure out a way to return to Durum - only to discover that when the homefront turns into the front lines, things are more dangerous than they seem.
