MARK OF A DEMON is a great Urban Fantasy/Paranormal Mystery- It's fast paced and hard to put down. Diana Rowland really made a great new series with fresh ideas. I took to the protagonist Kara who is a Louisiana Homicide Detective and a demon summoner. I like how she is in both the human world and demon world so you are always busy and on edge. Her first case as detective has her connecting to her past and her new demonic lord Rhyzkahl who is unearthly beautiful and just very deadly.
