Song of the Cicada: Demon's Waltz, Book 1 (Unabridged‪)‬

A man, a woman, and a demon collide in the 21st century. Everyday city life begins taking strange turns for Joss. He watches in horror as his friends and people around him are lost to violent deaths. Neighborhood cats are being slaughtered for blocks around his home. Not sure where to go or who to turn to, he asks his neighbor, a young wiccan for help. Life gets even stranger and more violent once they join forces. 

With their homes in flames, they flee the city on an antique Harley Davidson hoping to escape the evil pursuing them and end up in a relationship much deeper than either expect. Their flight takes them deep into the Appalachians, but too late they realize this was intended. With their lives at risk, they confront the demon on a moonlit mountaintop in a storm-wrecked chapel.
