When Homicide Detective Kara Gillian finds traces of arcane power on a body, she quickly realizes that this is no ordinary murder. The serial killer known as the Symbol Man is a nightmare that Beaulac, Louisiana thought had ended three years ago, but now he's back for an encore and leaving every indication on the flesh of his victims that he is well-versed in demonic lore.
However, Kara is a Summoner of Demons, and may be the only cop on the city's small force who can stop the killer. Able to see and interact with a world most people can't, Kara must draw on her skills as a police officer and master of the arcane to stop the Symbol Man from killing again and possibly summoning something even she can't control.
But with a demonic lord of unearthly beauty and power haunting her dreams, and a handsome yet disapproving FBI agent dogging her waking footsteps, she may be in way over her head....
The Blood of the Demon- Diana Rowland
The serial killer known as the Symbol Man has been dealt with, the demonic lord Rhyzkahl is no longer invading her dreams, and Detective Kara Gillian is doing her best to get her life back to normal after being kind of dead for a while.
Unfortunately, there's little about Kara's life that is ever normal or simple. As a skilled summoner of demons, she's hoping to use her arcane abilities to retrieve her aunt's essence and restore it to her body. But when Kara discovers that FBI Agent Ryan Kristoff is somehow known to the demonkind--and not in a good way--old doubts surface and new problems emerge. Moreover, her investigations into the deaths of several seemingly unrelated victims reveal disturbing links to the arcane, with unsettling similarities to her own situation.
But matters get more complicated when she discovers other links between the victims, leading her into a morass of political corruption. And it doesn't help that Rhyzkahl has asked her to be his own summoner, a commitment that could have quite a few advantages and plenty of pitfalls. Politics--whether among humans or demons--is a dangerous game with very high stakes, and Kara is learning that lesson the hard way.
