Shadowbeat — Crymsyn Hart

Ramos had never listened to the drums before Alisa crossed his path, nor did he cross the path of the demon who he shared his town with. However, when Alisa came to help her sister, something about her drew him. He had to keep her safe even though the demon had first claim.

Alisa just wanted to help her sister fix up the new house she bought. With the townspeople acting weirder and her sister going a bit whacky, Alisa turns to the only man who can help her. Ramos.
Together they face the darkness in the town. When the drums start, Alisa is drawn to them to learn how she is the key to defeating the demon even if it means paying with her soul.
