In a city where monsters hide in plain sight, love may be the most dangerous instinct of all...

Wolf shifter Conall, a battle-scarred Firebrand warrior from the Aeternal realm of Scath, is on the edge of turning feral when he is assigned to the NYPD to solve a headline-making murder on Earth. His partner is Reyna Todd, a driven homicide detective who has never worked with a non-human. As bodies with ravaged throats pile up from Manhattan to upstate New York, Con and Rey probe a sub-culture of vampire-wannabe clubs, sex resorts, and shadowy hangouts-while fighting an attraction that flares into an all-consuming bond.
