The Sentinel Mage (Volume 1)

In a distant corner of the Seven Kingdoms, an ancient curse festers and grows, consuming everything in its path. Only one man can break it: Harkeld of Osgaard, a prince with mage's blood in his veins. But Prince Harkeld has a bounty on his head - and assassins at his heels. Innis is a gifted shapeshifter. Now she must do the forbidden: become a man. She must stand at Prince Harkeld's side as his armsman, protecting and deceiving him. But the deserts of Masse are more dangerous than the assassins hunting the prince. The curse has woken deadly creatures, and the magic Prince Harkeld loathes may be the only thing standing between him and death.
