Unholy Obsessions by C.M. Radcliff

Selene Hayes was the daughter of a notorious serial killer.
And she was designed to keep his legacy alive.
She danced in the shadows, embracing the darkness within.
Revenge was her motive and she didn’t hesitate to extinguish the monsters from her past.
Except for Onyx–he was her monster.
Onyx Davers met Selene when they were both thrown into the foster system as kids.
She saw him for what he truly was–a killer–but she looked at him like he was a God.
From the moment he laid eyes on her, he knew she was special.
He knew she was like him.
He knew she would be his…
And he would end anyone who tried to tear them apart.
