Her Soul for Revenge by Harley Laroux

Juniper:
After a cult tried to sacrifice me to their wicked God, I went on the run, doing whatever was necessary to survive. Until a demon offered me a deal: give him my soul and he’ll help me claim the vengeance I seek. Blood will be spilled, and the monsters I once ran from will soon be running from me. But damning my soul was just the beginning – it’s my heart the demon wants next.

Zane:
I’ve been hunting souls for centuries, but she’s the ultimate prize – vicious and feral, with a broken soul as dark as my own. I thought claiming her would be a simple game, but Juniper is far from simple. I chose to follow her on a path drenched with the blood of her enemies, but it’s our blood that may be spilled next. As an ancient God wakes from Its slumber, neither of us may survive.
