A Sip of Sin by M.C. Roth

One man is possessed by a demon, the other a centuries-old vampire. Can they find love when they’re unknowingly mortal enemies?

Hollen’s luck is running out. With a chatty demon named George trapped in his head, he can only hold down a job for a few days before getting fired. When he stumbles upon a strange teahouse that’s only open at night, he discovers demons aren’t the only perilous things in this world.

Cruising through the monotony of his centuries-long existence, Munro’s life is forever changed when Hollen crashes into his teahouse, soaking wet and full of fire. But Munro has no idea that Hollen is haunted by George’s thoughts and that the demon will change both their fates.

Secrets are carved into the wooden rooms of the teahouse, but none are so lethal as the ones of Munro’s and George’s pasts.
