Captive Spirit (The Dark Crescent Sisterhood #4)

Trapped by temptation, bound by desire
 
Saving humanity from the supernatural has been challenging lately—even for a well-trained earth Sybil like Bela Argos, who must harness the magic of a fractious group of warrior sisters and battle a new wave of paranormal attacks. Another challenge is Duncan Sharp, the hunky NYPD detective who might turn into a demon overnight and devour Bela in her sleep. Still, the darkness taking over Duncan’s body can’t stop the molten heat unleashed by the intense attraction between them.

Duncan has two major problems: First, he has the soul of a suspected serial killer hitching a ride on his vibe. Worse (yes, worse) he’s got a demonic fever raging inside that promises a world of hurt for everybody, especially Bela. Now he’s all about getting even with the demons that put this freak curse in his blood—satanic forces that dare to unleash their savage lust on Duncan’s soul, his city, and the woman he loves.
