McKenzie Parker has a lot on her plate like the average high school student. But one unfortunate day at a diner she meets her mate. And he just happens to be King Thayne the devil's right hand man- no exaggeration. He's a demon, he's not just any demon; he's the Demon. The most absolute, without a doubt most powerful being on Earth. Complications arise when they start to get closer, as she learns about him she can't help but think that he's extremely dangerous. Well obviously he's a demon, who wouldn't? McKenzie doesn't want to be hurt, emotionally or physically, but is that really possible when your mate is an emotionless, cold, reserved being who doesn't know how to carry on a proper conversation due to a couple millennium of constant working for the guy downstairs?
