With the help of her pixie partner Jenks and Detective Glenn, Rachel must deal with demons, the elf Trent Kalamack and master vampire Piscary, who along with angry Weres, struggle for possession of the artifact. Meanwhile, a serial killer is on the loose and Rachel's alpha werewolf pal, David Hue, becomes the prime suspect of the FIB (aka the human-run Federal Inderland Bureau).
