FBI profiler Jace Valchek was pulled into this parallel realm to hunt for Aristotle Stoker, a human serial killer who preys on vampires and werewolves. Now she works for the National Security Agency of the Unnatural States of America - and her boss is a vampire.
At a bizarre crime scene, Jace finds a bloodsucker murdered by magic, fried to the bone and dressed in the costume of the comic book hero the Flash - a character who isn't supposed to exist here. Comic books have been outlawed for their powers, including crossover spells like the one that transported Jace to this world. Soon, she's following a trail of dead bodies into the sinister underworld of black-market comics - where a deranged madman gives new meaning to the term 'super-villain.
