Finders - Finders Ghost Hunting, #1

Demonologist Luke Melloy has seen the face of pure evil. He's fought it and sent it back to hell. It's what he does. To Claire Westin, ghosts and demons are just great television and good for ratings. When she's faced with the truth Luke has seen, her reality is turned upside down as the two are swept into dire straits moments after they meet. Desire sparks between the unlikely pair, throwing their hearts into chaos with a love neither of them expected nor wanted.
  When the Demon targets an unsuspecting Claire with his wrath, Luke finds his focus split between his oath to God and the awakening of his heart. Together, can they face the ancient evil and defeat it, or will they lose everything?
