A promise of fire
(Book)

"Kingmaker. Soothsayer. Warrior. Mage. Kingdoms would rise and fall for her...if she is ever found. In the icy north, where magic is might, an all-powerful elite--ruthlessly guided by a glacial queen--has grown to dominate the world. Now rebellion is stirring in the magic-poor south where, for the first time in memory, a warlord has succeeded in uniting the tribal nations. Stuck in the middle is Cat, circus performer and soothsayer, safely hidden behind the harmless illusion of the circus. Until someone suspects she's more than she seems...Captured by the southern warlord, Griffin, Cat's careful camouflage is wearing thin. For how long can she conceal the true extent of her power? Faced with dragons, rival gods and the traitorous longings of her own heart, she must decide: is it time to claim her destiny and fight?" -- Page [4] cover.
