Realm of Darkness

He's the rising star of the Paranormal Investigation Agency; she'd love to burn it to the ground.
Tria Winters plays the part of the loyal agent well, but she's nothing short of a prisoner. When the Agency is brutally attacked, she and her cousins should have taken their chance to run, but to her surprise, there are people she isn't quite willing to turn her back on.
It's obvious to Gray that Tria and her family are trouble, but they're the only ones who could fight off those who wish to destroy the Agency. He needs to stay with them.
Even thought their plan may lands them all in Hell.
Each book in The Infernal Three trilogy may be read as a standalone.
