Cursed City (Shadow Detective Book 1)

Demons murdered my parents when I was eight. Turns out my folks were paranormal investigators and Hell always settles its scores. Naturally I decided to join the family business. 

 

For two decades I've studied the occult and traveled the world fighting monsters. Vampires. Shifters. Demons. Ghosts. I've faced them all. But my biggest challenge lay ahead...

From the moment Celeste stepped into my office, I knew she was in trouble. Black magic trouble. Her father had promised her soul to a powerful demon on the day she was born. Now, twenty-one years later, the forces of darkness were gathering to collect their long-awaited prize.
  
Guess who's about to pick a fight with the Devil himself...
