Dark Urban Fantasies are set in some variation of current times with
real-world urban settings as opposed to fantasy set in imaginary worlds.
They incorporate elements of fantasy, romance, and horror. These stories
will often have supernatural beings, often demons, vampires and werewolves.
These beings are potentially sympathetic with human motivations.
I recommend the following authors:
Illona Andrews (Kate Daniels series)
Patricia Briggs (Mercy Thompson series)
Steven Green (Nightside series)
Kim Harrison (Rachel Morgan series)
