Rise Of The Raven. Raven Hills Coven

For centuries, the Raven Hills Coven has awaited a time when the prophesied children would arrive, heralding in the rise of the raven. As each of the four sisters who were born with the mark reaches their maturity, they ascend into their full powers. Alyza, the oldest sister, has eagerly awaited this time, confident that she has what it takes to embrace her new reality. She never expects her destined mate to show up, nor does she anticipate that it will be a demon from Hell.
What in the goddesses name was Mother Nature thinking?  As the second in command to the dark lord of the underworld, Christian knows his purpose is to ensure that new demons become terrifying so they can handle the jobs they're assigned. When he wakes up in a completely different dimension where people laugh, joke, and smile, he reaches out to his lord only to hear nothing back in response. When the couple realizes that they're intended mates, they must navigate not only that minefield but try to figure out why they were paired with each other.
