Dark Consort by A. D. Roland
Ruler of a withering kingdom, Ceron has come to terms with the fact that the only way to save his country is to carry on with one of his ancestors' worst traditions--the kidnapping and sacrifice of a mage to revive the dying magic of Aichinn. Through his short reign, he's fought hard to bury his hateful legacy and create a new, peaceful rule. The demons that have plagued his bloodline, however, have other plans. Vile plans. They want blood and war, death and destruction. Even as he fights them, tooth and nail, he realizes he can't fight them forever.
Kaeda just can't get it right. A healer mage in the lush, bountiful Northlands, no matter of training seems to awaken more than a trickle of her magic. When the mysterious visitor from a southern state offers her an escape from the looming banishment, she takes him up without a second thought. Unfortunately, the stranger isn't who he says he is.
He's the dreaded King of Nightmare and Shadow, the Lord of the Goblins, the Dark King Ceron. And he wants her. Despite being kidnapped, imprisoned, and deceived, Kaeda discovers she's meant for so much more than what Ceron intends. The very land of Aichinn embraces her, and her natural abilities flood forth. The dying kingdom has a chance to live again. With the awakening of the land's magic, Ceron's demons rise in full force, determined to wield the burgeoning power as their own.
Kaeda is Ceron's only chance to save Aichinn--if he doesn't destroy her first.
