Mark of the Demon

by Diana Rowland

Published 1 January 2009
Cop and conjurer of demons, she’s a woman in danger of losing control—to a power that could kill. . . .

Why me? Why now? That’s what Beaulac, Louisiana, detective Kara Gillian was asking herself when an angelic creature named Rhyzkahl unexpectedly appeared during a routine summoning. Kara was hoping to use her occult skills to catch a serial killer, but never had she conjured anything like this unearthly beautiful and unspeakably powerful being whose very touch set off exquisite new dimensions of pleasure. But can she enlist his aid in helping her stop a killer who’s already claimed the lives—and souls—of thirteen people? And should she? The Symbol Man is a nightmare that the city thought had ended three years ago. Now he’s back for an encore and leaving every indication on the flesh of his victims that he, too, is well versed in demonic lore.

Kara may be the only cop on Beaulac’s small force able to stop the killer, but it is her first homicide case. Yet with Rhyzkahl haunting her dreams, and a handsome yet disapproving FBI agent dogging her waking footsteps, she may be in way over her head. . . .

Blood of the Demon

by Diana Rowland

Published 1 January 2010
BETWEEN HEAVEN AND HELL, MAN AND DEMON, SHE’S ABOUT TO FACE THE ONE THING SHE MAY NOT BE ABLE TO SURVIVE.
 
Welcome to the world of Kara Gillian, a cop with a gift. Not only does she have the power of “othersight” to see what most people can’t even imagine, but she’s become the exclusive summoner of a demon lord. Or maybe it’s the other way around. The fact is, with two troublesome cases on her docket and a handsome FBI agent under her skin, Kara needs the help of sexy, insatiable Lord Rhyzkahl more than he needs her. Because these two victims, linked by suspicious coincidence, haven’t just been murdered. Something has eaten their souls.

It’s a case with roots in the arcane, but whose evil has flowered among the rich, powerful, and corrupt in Beaulac, Louisiana. And as the killings continue, Kara soon realizes how much there’s still to learn about demons, men, and things that kill in the night—and how little time she has to learn it.
