Steelflower in Snow - The Steelflower Chronicles, #3

Kaia Steelflower meant to spend her winter resting, but the high price upon the head of her barbarian companion Redfist has drawn her out of safety and through the northern passes to the Highlands. Bandits, blood, and treachery, Kaia's seen it all before. But something else lingers in the snowy wastes north of the mountain Rim. Ancient power has found a new host, plans have been laid for rebellion, and the giants of Skaialan do not take kindly to foreigners.
Saving Rainak Redfist will demand all the skill, strength, and cunning the Steelflower can muster; saving herself-and her new princeling husband-might be impossible. Winter in the Highlands is brutal, and it's only just begun.
