"In a world where magic is intrinsic to the fabric of everyday life, two kingdoms, centuries-long enemies, have long sought a powerful magical weapon that will win them lasting dominance. But neither realm is ready when they are both attacked by the Bottom-Dwellers, a bitter people whose own land was destroyed, and who now live only to take vengeance on those they blame for a wretched life in the storm-tossed abyss they inhabit"--

The known world floats upon the Breath of God, a thick gas similar to Earth's oceans, with land masses accessible by airship. The largest of these land masses are ruled by the rival empires of Freya and Rosia. Magic is intrinsic to the functioning of these societies, and is even incorporated into their technological devices. But now a crucial scientific discovery has occurred that could destroy the balance of power--and change the empires forever....

"The thrilling conclusion to the swashbuckling Dragon Corsairs series. Kate and Sophia and their dragon Dalgren form a desperate plan to free Phillip from prison. Thomas is crowned king and discovers a plot by King Ullr to invade Freya. And Henry is forced to flee to the Aligoes where he makes a discovery that could change the fortunes of his beleaguered nation."--Publisher's description.
