Nyx’s Blade by Serena Simpson

Nyx hunts the evil that preys on women to atone for a sin that’s not hers. After her last hunt, she’s determined to go into retirement. Meeting Blade a male that’s so obviously alien wasn’t in her plans. When she gets called into the dream corridor to help him fight, retirement is the last thing on her mind.
Blade never expected to be called to Earth. His plans were to die or to fade away until no one remembered his name. That might have happened if he didn’t meet Nyx. Now they have an enemy in the dream corridor and a rising passion between them.
If she can get over her refusal to date an alien male and he can find his soul, they may be able to work together to save the young males of the earth. Times running out and whatever is lurking in the dreams of children are ready to step out of the shadows to destroy the world.
