And they thought catching the serial killer was difficult... Psychic Ariana Ryder just completed her probationary year and is now a full agent in the FBI's Special Division Force, a semi-secret branch that investigates paranormal crimes. She's got a great, if strict and strictly yummy, boss, a vampire for a boyfriend, and yeah, that has its issues and politics, but overall, life's lookin' pretty good. The director, in a bid to score political points, puts Ariana on interrogating famous serial killer JB Truck, aka The Puzzle Master. Truck's been in prison two years and the authorities still can't figure out who all his victims were or where his vast resources came from. Ariana's mission is simple, get visions off the psycho until they get the information they need.But nothing's ever simple when there's magic afoot. The vampire queen's gunning for Ariana, there's a mysterious new shifter in town who needs a psychic's help (and is way too flirty considerin' she's a lady with a boyfriend), and Truck's got a few tricks of his own... And he didn't end up in Nashville by chance.
