Demons are Forever — Wynne Hayworth

Evolution got an astronomical kick in the pants. Now it's kicking back… Afterglow. Our world is changed. Mutated. Now home to humans who possess DNA belonging to creatures once thought to be only the stuff of legends. So what if the neighbor howls at the moon every month? No big deal as long as he mows his lawn. A savage killer munching on helpless victims, however, is a big deal to Detective Buck Shand. Buck is thinking less legend and more nightmare as he surveys the most recent in a series of brutal slayings. It's beyond even his special talents, and he's going to need help with this one. It arrives in the shapely form of Dr. Lian Herrick, a woman with her own form of Afterglow mutation-a demon that will shake Buck's everyday world to its foundations and turn his brain inside out. Will their combined skills be enough to track and stop a savage killer? Possibly. If they can keep their minds on business and their hands off each other long enough to lure a beast who feeds on sex-then kills for pleasure.
