Eternal Kiss of Darkness (Night Huntress World #2)
Chicago private investigator Kira Graceling should have just kept on walking. But her sense of duty refused to let her ignore the moans of pain coming from inside a warehouse just before dawn. Suddenly she finds herself in a world she's only imagined in her worst nightmares.
At the center is Mencheres, a breathtaking Master vampire who thought he'd seen it all. Then Kira appears, this fearless, beautiful . . . human who braved death to rescue him. Though he burns for her, keeping Kira in his world means risking her life. Yet sending her away is unthinkable.
But with danger closing in, Mencheres must choose either the woman he craves, or embracing the darkest magic to defeat an enemy bent on his eternal destruction.
