The Advisor's Apprentice — Mandy M. Roth

Sought as mates because of their ability to wield magick, the Antistitas priestesses had been hunted almost to extinction by the warlords determined to possess them. But Teigen had no intention of becoming a mere possession, of no more value to the males who caught them than their horse.

Alerted to the attack on the village of Sabian, the king sends his advisor, his brother, Andrija to search for his wife's sister, Teigen, and bring her to safety. From the moment Andrija captures her, however, he can think of nothing beyond claiming her for his own.
