Ever Dark by Kensie King

I know there are men out there that are more than human. Men with powers beyond my wildest imagination. But it’s my job to find them, not fall in love with them.
After one of my best friends revealed to me his special powers, I was amazed but not shocked. After all, I’ve seen what he can do. He’s faster and stronger than any human and heals in the blink of an eye. And when he tells me there are more like him out there, I’m intrigued.
Intrigued enough to get a job working for a best-selling author and the sexiest man I’ve ever seen. But I’m not just trying to discover his power, I’ve also been asked to find out if he’s responsible for the local murders that are plaguing our city.
I thought it would be easy until my heart gets involved. Now I’m at war with myself and another potential threat. Is the man I love one of the good guys or is he the enemy?
