But one man stands out, more mysterious and attractive than all the others, a Bilarrian Mage named Vox.From the moment Vox meets Emily, he burns to claim her as his mate. He is running from obligations back home, and choosing a human mate will greatly complicate the situation. But Vox doesn't care. He's found the one woman who can complete him, and he's just as determined to win her devotion. All that stands in his way is Emily's absolute insistence that she has no interest in romance of any kind. Vox welcomes the challenge and uses every sensual technique he knows to wear down Emily's defenses. Their future will be long and happy, if she can just learn to trust him.
