The Seventh Sigil

In this swashbuckling epic fantasy series from New York Times best selling authors Margaret Weis and Robert Krammes, daring dragon-riders fight to save a uniquely magical world from destruction by vengeful outcasts.

In a magical world, two enemy kingdoms have long sought a weapon that will win lasting dominance. But then both are attacked by the Bottom-Dwellers, bitter people whose own land was destroyed. Using contramagic strengthened by blood sacrifice, they threaten to bring down whole cities. Freya and Rosia must put aside their age-old conflict to defend themselves.
