Who is the murderer who has been torturing and killing ley line witches? Rachel Morgan, broke as usual, is drawn into the investigation, certain that the perp is her nemesis, Trent Mackalack. She enrolls in the university class taught by one of the best known ley-line witches around, and the prime suspect in the case. We are introduced to the major Vamp in town who, strangely, runs a fancy pizza restaurant. He is an ancient and very powerful. He also wants Ivy to be his scion, replacing his current number two, the handsome and seductive Kisten. Rachel continues to do battle with Algaliarept, a shape-shifting demon who seems determined to bring her under his control. She also contends with her boyfriend, Nick, who seems a bit too knowledgeable about dark magic for his own good. But he does help her in her work, and accidentally becomes her familiar. It is a fun ride, and the world that Harrison has created grows with each new work. If she can keep this up she may have a very lucrative franchise. A fun read with no (that I can tell) presumptions to literature.
