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. Using contramagic strengthened by blood sacrifice to attack the world above, they threaten to bring down whole cities, or even the island kingdoms themselves. Freya and Rosia are forced to put aside their age-old conflict to defend themselves, or risk losing everything.
As the Bottom-Dwellers' contramagic eats away at the magic of the dragons that helps protect the world above, a former dragon-riding hero gathers a ragtag group to form a new dragon brigade, the one desperate hope of the two kingdoms to defeat the fiends who threaten their world. As the effects of contramagic bring the world ever closer to disaster, the new dragon brigade fight the vengeful adversary. Their high-flying heroics will be to no avail, though, unless they can somehow uncover forbidden knowledge, long hidden by the Church, without which they will never be able to prevent the world's destruction.
Margaret Weis and Robert Krammes deliver yet another exciting dragon brigade adventure in Storm Riders.
