The books feature werewolves, witches, necromancers, sorcerers, and vampires struggling to fit as "normal" in today's world. The series also includes novellas and short stories, published online (and one in an anthology).
Actors Michael Luckett and Greg Bryk previously worked together on another similarly-themed project. They were both in the 2010 film Red: Werewolf Hunter. Bryk played a character named Michael Sullivan while Luckett played a teenage boy in the film.
